I have a theory about The Cahill Files. As we know, the first three ebooks were bound into one book, Spymasters, and released on May 1st. It says Book 2 at the bottom of the cover. What if they were to release a book 3? The last ebook, Silent Night, is the only one left, and is too short to be in a book by itself. Now the only other books not to be released in stores is Rapid Fire, also Christmas themed. All The Cahill Files books are short stories, as are Rapid Fire, so what if Book 3 of The Cahill Files (Which they can call Silent Night still) contained Silent Night and all 7 Rapid Fire? Makes sense to me.
