Warning: do NOT pick up this book if you have (a) life responsibilities, (b) less than 24 hours to commit to reading it continuously, and/or (c) the inability to walk away from a stirring and compelling storyline. I should have taken my own warning and saved this book for vacation... It should go without saying that I loved this book-I was on the edge of my seat and I caught myself almost praying for the characters (I modified my prayers and prayed for those who may be caught in similar situations). This is a fast-paced thriller by a Catholic author, though calling it a "Catholic book" makes it sound like faith is shoved down your throat, which it is NOT. You could let your teen read it, but make sure you treat yourself to the adventure of reading it before you do! Highly recommended from me!
