The Devil We Know was an action packed whirlwind of a book. It’s the fifth book in the End of World series, and could be read as a standalone. But I would recommend reading all the books so you know all the characters in the this book. I was loving Matt and Jessica’s relationship, it was explosive from the start. And when Jessica wasn’t taking any of Matt’s disappearing act and got reinforcements. The lengths Jessica went to, to make sure Matt was safe showed how much she cared for him. And all the secrets on both sides that came out had my head spinning. The you know the best part of this book and the series? The found family, everyone had each other’s back no matter what. This book had action from page one and it lasted all the way through, and I loved every second of it.  I really hope we hear Kaian and Camilla’s story in a future book, because the love/hate between them was so hot.
