This book was pretty compelling, right up to the end.
Sylvie, a bright and motivated 14 year old, lives in a pretty discouraging home. Her parents "heal" the haunted. Her older sister is a rebel. The book is a murder mystery. Early in the story Sylvie's parents are murdered in a local church. Sylvie may be the only one who has answers to the identity of the real murderer.
Over all I enjoyed the book. The strands of the mystery are many and interwoven. I would have personally chosen a different ending, but that is because I am always looking for cross-over books (adult books for young adults). I will hesitate to recommend this book without forewarning (in my conservative state).
One strength of the book is that there are many adults and a few young adults who actually support Sylvie and are actually somewhat helpful. The main characters are relatively nuanced. Generally I can recommend this as a summer read.
