I usually hate prologues, but this book has a good one. It's not even really a prologue, since it contains the story's inciting incident—it's only labeled a prologue because it takes place nine years before the start of the first chapter. Anyway, I'm definitely very intrigued by the sample—the writing is clean and straightforward (just how I like it), the story sounds fascinating, and the characters are compelling. I'm also really interested in this book because I love stories about siblings—I really want to see where their relationships go from here!
