 Becca's little brother, Ryland, is different. He hears voices sometimes. Most people think he's crazy, and Becca constantly has to protect him from being locked up or medicated. When representatives of an Irish school tell Becca that Ryland isn't crazy, just special, and they want to help, she's obviously skeptical. But she agrees to let Ryland travel to Ireland on one condition--she goes with them. What follows changes her entire life and everything she thought she knew about herself, her family, and the world. 
 Comparisons of this book to X-Men abound, and they're not far off, though the Holders' powers are balanced by a weakness that they usually manage to offset with a talisman of some kind. However, that doesn't mean that the book is a complete knock-off of X-Men at all; personally I found the characters in The Holders to be much more relateable than most comic book characters. 
 I struggled with how many stars to give this book because on the one hand, it's well-paced and kept me reading, but on the other hand it's fairly predictable and contains several YA cliches. The characters were well-developed and believable, and though the first half of the novel is mostly character development, the real plot kicks in just before the character development starts to get too much. There's a fairly major plot twist midway through the novel that I figured out pretty much immediately when the setup for it was introduced, though it doesn't seem that Scott was really trying to hide it from us. 
 The romance, while sweet, bugged me in that Becca seemed aware that she was living the YA trope of insta-love and trying to refuse to give in to it, but failed miserably. Granted, later there was a mystical reason why she failed, and the relationship did develop through friendship before it got really serious, but her thinking on the matter and refusal to be a teenage girl stereotype seemed very much like the author trying to assure the reader that this wasn't going to be like every other YA romance. At least there wasn't a triangle. 
 Those complaints aside, I enjoyed the book and will most likely read the next one when it's available.
