Gretchen is obsessed with puzzles, and she's an odd person. Lucy needs the friendship, so she tolerates Gretchen. Unfortunately, Gretchen isn't just odd. She has serious problems, which Lucy and her mom encounter during their time on the Sabin farm.This book is captivating. I spent several nights reading until I couldn't keep my eyes open. It has so many twists and turns. I enjoyed the ups and downs.I gave it four stars because I felt like the chapters labeled "Mother" didn't get the proper attention they deserved in the first half of the book as a reader because I was reading them from the viewpoint of Lucy's mom not the proper character which made me feel like I missed out on a lot of context. To keep from spoiling the read, I'm not going to elaborate further.That being said, it was thrilling to read, and I would recommend it for those needing a little adventure.
