Considering I have the memory of a goldfish, I really appreciated the summary of important events from book 1 incorporated in the first pages of this sequel. It picks up almost exactly where book 1 left off and delves straight into the story, with all of the characters I've grown to adore: Jack, Ethan, Will, Willoughby, Opie, Opal, Hoke...
Unfortunately, it's not quite as well-edited as the first book, but the handful of errors I noticed barely registered in the midst of such a gripping story. I did feel like I missed some details in regards to Opal's journal, and I wonder if I should have read the short story before delving into this book.
So far, this series reads like the author threw The Hunger Games and Divergent into a blender with a pinch of surprises and a dash of her own flair. There are a few parallels, but these books are well-written and engaging, and I really, really like them. And then there is the Big Twist, followed by the worst cliffhanger ever. Definitely have book 3 on hand when you finish this one! Wow.
Note: I received a free copy of Betrayal from the author in exchange for an honest review.
