I enjoyed reading this story, but keep in mind that it is the first in a series so it does end with questions and a cliffhanger or two.
Book One focuses mostly on character development with primary emphasis on the main character, Katrina, who suffers from amnesia. Although she has no idea who she was before, her past is gradually revealed through dreams and flashbacks (but I won't say any more about those, too many spoilers). Hostile supernatural enemies, unknown past, a lost sister that haunts her dreams, what more could you want?
If you like reading about young people, vampires, werewolves and mystery, you'll probably enjoy this book.
Again, this is the first in a series and is not a standalone book, but that didn't stop me from enjoying it.
