Dangerous Boys by Abigail Haas is one of the best Young Adult books I've read this year. The other would be Haas' debut novel, Dangerous Girls. I'm going to admit it: when I think of YA books, I tend to associate the genre with lower quality writing. That was not the case here. The writing in this novel is on par with quality adult literary fiction, and really does a service to a genre that is often discredited. 
 Part of the fun of this book is gathering your bearings in the confusion, and honestly, even the cover description spoils some of that for the reader, so I won't say much about the story, except this: The book begins with one of the Reznick brothers holding a knife, with Chloe and the other brother pleading with him not to hurt them. This is followed by a 911 call in which Chloe reveals one of the boys has been stabbed. Which brother was stabbed? Why? How did these characters get to this place? The rest of the book unravels the mystery through time jumps and slow progression of the relationships between the characters. 
 I love books with surprise endings, so the promise of that immediately drew me to this book. And luckily, the author's deft handling of plot, description, and atmosphere had me riveted to the very end. The only problem I had was that Chloe's character seemed a little inconsistent and her development a bit unrealistic (and maybe a little too convenient for the plot?), but I can forgive that for the way her shift in character led to a powerful ending. And although I was promised a surprise ending, it wasn't all that much of a surprise for me, but I can forgive that for how well it was done. 
 If you are inclined to try out a lesser-known but thrilling Young Adult book, I would highly suggest this book.
