Overview of the Generations[]

Gideon Cahill - 1507 (By Rick Riordan)[]

Travel back to the days of Gideon Cahill and Damien Vesper to read about the rivalry that shattered the Cahill family...and changed the fate of the world.

Gideon comes to Damien Vesper's house. Gideon tells Damien he hasn't found a cure to the plague but he has found something. When Gideon does not tell Damien it is the serum, he releases a mechanism in which the roof collapses on Gideon to kill him. But Gideon inhumanly quickly moves out of the way. Balthazar comes in to check if everything is alright. Damien notices his bleeding knuckles. Gideon lies that Damien could have done it too, when in reality he had made his abilities more enhanced through the serum.

When he goes home, he knows he only has about 24 hours to finish the serum before he dies from the Master Serum. Then, he tells his family about the serum he has made for the plague, (the Black Death). He gives each of the children a part of the serum. He says that he has given each of the children the part of the serum that would enhance their natural abilities.

Luke would take the quarter that made him cunning and strategic, Katherine would take the part that would enhance her mechanical engineering and her inventiveness, Thomas would take the quarter that honed his sports abilities, and Jane took the part that would make her more artistic. Combined, Gideon said, would make the master serum.

Luke wants the master serum, but Gideon does not agree. Luke drinks his part of the serum, and because of his portion, has the cunning to break into his father's lab. He warns his father about Damien Vesper coming but it is too late. Damien is already there and enters the lab just as Luke leaves. Luke gets his family out of danger, but just then, the house explodes. Gideon was threatened by Damien because he wanted the serum. When Gideon refused, he sent his men Balthazar and Craven to stop him but Gideon blew his lab up to keep the secret of the serum safe.

The Cahill children blame Luke for the explosion, even though it was Damien's fault. Luke leaves, followed by Jane, who hoped to keep him from leaving. Katherine and Thomas are angry at both of them, and decide to leave as well, leaving Olivia with unborn Madeleine, dead Gideon, and Damien Vesper.

Olivia doesn't tell Vesper the truth about the ring, saying that Gideon's ring, which Damien wanted, was a token of Olivia's love for Gideon. Damien, of course, despised love and anything of the sort, and flatly refuses it after Olivia (cunningly and sarcastically) offers it to him. Damien sensed that a grieving mother and wife was more dangerous than any monster he could create, so he left Olivia, Madeleine, and Gideon alone, leaving the threat of watching them hanging in the air.

Madeleine Cahill - 1526 (By Peter Lerangis)[]

The story begins in a class where Madeleine Babbitt is watching as the last of her classmates fall unconscious because of her sleeping formula her classmates forced her to do. She thinks of lies...She knows all her life is made of lies. Even her name is a lie. Her name is not Madeleine Babbitt, or as her classmates call her, "Maddy Babbitt, scared as a rabbit!" Her real name is Madeleine Cahill.

Olivia Cahill is killed by Damien Vesper. Madeleine then seeks out Luke. She finds a job as a governess for Luke's son, and explained to Luke that she is his sister but Luke did not believe her because this happened multiple times before when someone lied of being Luke's long lost family member. However, he


Madeleine Cahill

thinks she could be his sister, and remarks how she sounds like Katherine and has Jane's mannerisms.

Afterwards, it is shown how she escapes her imprisonment and how it inspired her to found the Madrigal Branch. Throughout this part of the book, it is explained how Madeleine has talents from all 4 of her other siblings, called a jot of Jane, a cut of Katherine, a lick of Luke, a touch of Thomas, and her own talent is called the magnificence of Madeleine.

Grace Cahill - 1942 (By Gordon Korman)[]

Follow thirteen-year-old Grace Cahill as she embarks on her very first mission during one of the most dangerous moments of the 20th century.

Grace is playing with her younger brother, Fiske. We meet Beatrice and find that she hates Fiske because their mother, Edith Cahill, died giving birth to him. Grace decodes a Morse code message from the light-post outside that warns their father, James Cahill, of the Vespers trying to regain Gideon's ring.

She goes to Casablanca, where a war is occurring to find George S. Patton. When she can't bribe any of the pilots to go there, she finds a man named Drago, who will take her to Casablanca for $20,000. When Grace only gives him $10,000 and tells him she will give the other half at the end of the trip, the man runs away. Angry, Grace kicks the man, runs to his plane and tries to get there herself. After several cries from Drago, he agrees to take her to Casablanca on Olga, which he tells her he named after his gun.

When they get to the war site, Drago is killed and tells Grace that Olga was not named after his gun but his daughter. He then tells Grace that he has not seen her since she was a little child but he hopes that she is going to be just like Grace. Grace struggles to right the plane and it crashes. When Grace wakes up, she realizes she broke her wrist. She escorted by the military to get a cast. She then goes to the tent of George S. Patton.

Grace tells Patton the information in the letter and Patton tells Grace about the Vespers—that they some aren't related by blood (similar to the Madrigals, like how they recruit people from other branches) but they all have the same goal—world domination.

Grace then tries to find the answer for the mysterious letter she found and sees that the letter was talking about the eye of a bull statue in the Torch Cafe. When she finds that nothing is in there, Patton tells her that a Vesper agent beat them to the ring. Grace sees a bulge in Patton's pocket and discovers that he is the Vesper agent.

While Patton is sleeping, Grace steals the ring and tells the guards that she is anxious to get moving and wants to go. The guards take her to Lisbon, where she is now under protected ground. When Patton wakes up, he discovers that he has been beaten by a thirteen year old girl and is infuriated.

Grace then goes home, reunited with baby Fiske.

Amy and Dan Cahill - Present (By Jude Watson)[]

Finally, flash forward to the present to join Amy and Dan as they prepare to fight their new enemy—the Cahills' historic rivals—The Vespers.

Amy and Dan go to Switzerland to retrieve Gideon's ring from Grace's bank deposit safe. However, a Vesper named Casper Wyoming continuously attacks them at the slope, endangering their lives and the future of Cahills everywhere. They escape him, and Amy is appointed by Grace as the keeper of Gideon's golden ring.

Dear Cahills,

I wrote six different drafts of this letter until Dan threw a cookie at me and said just to be blunt. So here it is: Our family is in danger.

We thought we were the only ones who knew about the 39 Clues. We were wrong. There's another group out there - the Vespers - and they're coming for us. If the Vespers get their hands on the Clues...the world doesn't stand a chance.

Dan and I are calling all Cahills, from every nation around the globe, to come together. Only together can we be strong enough for the fight that's coming.

Are you ready? Because we need heroes now and we're counting on you.

- Amy and Dan Cahill


  • This book has the most authors in the series.
  • In the back cover, the blue rectangle that usually says "Join the hunt at now" is replaced with: "The Vespers are coming and YOU must be ready. Find the Secret Vesper files at".

  • On page 138, Drago said to Grace: "Here is advice to pass to your grandchildren someday: Trust no one.", and she followed it, passing it on to Amy and Dan through William McIntyre.
  • There are four changes from books 10 and 11:

1) In Book 10, the logo appears to be made of glass and breaks. In Book 11, we can see red dots in the oval where the world logo was. In the inside cover, the red dots fill the empty oval, zooming into their place wherever they are, and finally, on the inside back cover, we can see that the red dots are what makes the new logo.

2) The font that is on most of the covers on the books has changed.

3) The blue hexagon that is on the bottom of each book cover now says, "Read the books. COLLECT THE CARDS. Play the game." There is no "Win the prizes."

4) Inside the book, instead of the title of the book on the right hand side, it says the author, one per chapter.
