Attention All Cahills! For 500 years, the Cahills have been the most powerful family in the world. For 500 years, they've protected the source of their power - the 39 Clues. And for 500 years, they've kept the skeletons in their past buried. Until now. Amy Cahill is cracking open the Cahill vault to reveal the family’s most shocking secrets. Introducing the Cahill Files, four brand-new Cahill adventures coming soon. Operation Trinity
Three stories trace the history of the world’s most coveted artwork, a masterpiece that’s been the target of a record seven theft attempts. The novel tells the story of Grace Cahill’s attempt to rescue it during WWII, and Ian and Natalie Kabra’s brush with it on their very first Lucian mission. Available wherever books are sold and as an e-book.

I was wondering if maybe the other two books could come out in paper as well, not just electronically. Some people do not own an e-reader to access them. Just a thought. Thank you.

I also though that it would be a really long wait till September for Shatterproof. Until I saw this post, I was only aware of the Trinity Files, which I saw for pre-order on Amazon. This new mini-series will make the wait much less tedious.

For some reason, I think Katniss Everdeen is a Cahill. Most famous and adventorous people were! If she was, I think she'd be a Tomas.

Well, I wish that I could remember the dates these books come out on. I wasn't on here all winter long and so I completely missed the release of The Dead of Night. I guess I was just so busy waiting for everything else in my life to happen that I completely forgot about 39 clues. But that's what happens when you're in high school and you're counting down the days to The Hunger Games, a new season of Doctor Who, a trip to Disney, The Avengers, you and your twin's birthday, The Hobbit, the start of a new cross country season :), and The Serpent's Shadow. Oh well! I' really going to have to find someway to remember Sep. 4th. hmmmmm... better get on that. Also, I'm pretty bummed out now because all of these stories are ebooks only. :( Whats wrong with a regular old book???
