First off, thanks to NetGalley for letting me have a copy of this book in exchange for an honest review.
As for the book, it's the first book in a paranormal series about a woman in our world who finds her life turned upside down when, due to unknown causes, lots of people start showing supernatural traits. Some become werewolves, other mages, or warlocks, witches, fairies, vampires, etc. She herself gains some witchy powers. At the start of the book, we learn that normal humans are trying to capture these supernaturals and use their blood to fabricate a serum that gives them temporary powers.
The book is ok. Characters are a little flat, save for two or three, more developed. The plot is predictable, and has some holes in it. There's no in depth explanation of the event that awakens latent powers in people. Also, the magic system, or power system, lacks complexity and internal logic. Dialogues are typical, and also the romantic parts fall short of expectations. The book is fast paced, though, entertaining with enough action scenes, and leaves you wanting more. Maybe the following instalments are better than this one.
