Let's give it up for Hannah Moskowitz! 
 Break is her debut novel, and a great one at that. It's a shorter book, but the storyline, action, and characters weren't lacking. 
 From the first page you are sucked in to Jonah's problems. The best part about Break (and, coincidentally, my favorite part of her other book Invincible Summer) are the characters. Jonah is desperate, and addicted to breaking his bones. He has a brother allergic to everything - this relationship was written perfectly. Jonah's other family members all fit together, and Naomi really made me mad for blindly helping Jonah - maybe if I had more of her backstory I would have understood her reasoning there. When I have strong feelings for most all of the characters (whether good or bad) I know that they are written well, which is the case for Break. 
 Like many others, I found the ending to be a little off, but Moskowitz's strong character writing made the book an overall hit for me. Reading about someone who breaks their own bones on purpose is not something I've read about before, but Ms. Moskowitz does an excellent job of setting the mood and showing how it would affect those around you. 
 Break's plot could be a little extreme for some readers, and there are some vulgarities (which fit well with the characters). This is a book I could see a high school boy wanting to read, which is a big accomplishment from a teenage girl/woman writer.
