The Unbound by Victoria Schwab
"Imagine a place where the dead rest on shelves like books.
Each body has a story to tell, a life seen in pictures that only Librarians can read. The dead are called Histories, and the vast realm in which they rest is the Archive.
Last summer, Mackenzie Bishop, a Keeper tasked with stopping violent Histories from escaping the Archive, almost lost her life to one. Now, as she starts her junior year at Hyde School, she's struggling to get her life back. But moving on isn't easy -- not when her dreams are haunted by what happened. She knows the past is past, knows it cannot hurt her, but it feels so real, and when her nightmares begin to creep into her waking hours, she starts to wonder if she's really safe.
Meanwhile, people are vanishing without a trace, and the only thing they seem to have in common is Mackenzie. She's sure the Archive knows more than they are letting on, but before she can prove it, she becomes the prime suspect. And unless Mac can track down the real culprit, she'll lose everything, not only her role as Keeper, but her memories, and even her life. Can Mackenzie untangle the mystery before she herself unravels?"- summary from Amazon
Schwab has done it again. I was so excited to read this sequel and she did not let me down; this follow-up is just as good if not better than the first book. I really hope there will be a third book. I can't let these awesome characters go! I love Mackenzie, Wesley, Roland, and so many others and I really enjoy spending time with them. Schwab's prose and Mackenzie's voice make this book hard to put down and I read it very quickly over a couple days. The stakes are higher in this book, and there's more action going on that keep the story compelling and fast-paced.
Overall, a fantastic follow-up and I think it's a good ending to the series if it ends up being that, but I so hope a third book will happen. Please check this series out; it's simply amazing!
