FOREVER, by Maggie Stiefvater, is the final book in The Wolves of Mercy Falls series and what an ending it is! We last left off where Grace shifted into a wolf leaving Sam, Cole, and Isabel wondering if she will come home in the summer... 
 This book was incredibly bittersweet. I've loved this series since the beginning and it's all lead up to a wonderfully semi-wrapped up ending for these characters. I say semi because the ending was a bit open-ended but not a complete cliffhanger. I thought about the lives of these characters long after I finished reading and I appreciated that. 
 Many story lines intertwined through this book. We learn a lot more about Beck and Sam's relationship and the reason Beck bit Sam. Cole and Isabel's relationship was tumultuous at best, but darn it I love those two. The chemistry between them was electrically charged and I loved their banter. Isabel's father was in charge of the hunt for the wolves and the race to save Grace, Cole, and the other wolves from an unfair death. Sam and Grace were adorable as usual. Sam's unwavering love for Grace kept her grounded after everyone thinking he was the cause of her disappearance in the winter. 
 I loved getting into the mind of the wolf in this book. I don't recall there being too much of that in the previous books so I appreciated it in this one. The fight to keep some humanity while still a wolf was the most challenging for Cole, Sam, and Grace. 
 All these story lines built up to an amazing ending to the book and series. I look forward to more from Stiefvater in the future.
