It was a good book (I like her writing style) but I found myself less excited when they weren't in the Greenway store anymore. I really liked that place! After the fast-paced and exciting book #2 this was kinda a letdown. It's a book that brings the series to it's end and although exciting at points it's not quite as good as book #1 and #2. I really liked her opening and I'm impressed by the way she started this book and #2 (Sky on Fire). It was a fun and different way to give the readers a summary of what has already happened. It was nice to not have this information spread over the first pages as that tend to get boring, especially when you just read the other books and remember what happened. 
 I didn't particularly care for the ending. It felt rush. (view spoiler)[The "evil" doctor who where set on killing Josie suddenly turned good when he found out who they were and then helped them through all of it. I never thought I would complain about a happy ending but the epilogue, to me, where just too sweet and everything just turned out too well. All their problems where solved and all the kids either found their parents or where adopted by one of the others parentes/ guardians (hide spoiler)].
