Before I even start writing I have to tell you- Kelley Armstrong is one of my favorite non-fiction writers. She is one of the few that I will pony up the $25 for a new hardcover book and not even blink because I read them over and over. I am TOTALLY biased.
Kelley has one large series of books she has written with all of society’s current favorite characters- witches, werewolves, vampires, half-demons and the humans who interact with them. Her new book  (which I just purchased on Amazon today) is going to wrap up their storylines. The book I just finished is full of short stories that are prequels to many of the characters in her novels.
I adored this book- so many great “how he and she met” stories and “this is how he became evil” stories. Once you fall in love with characters you want to know everything about them.
Since it is short stories it’s a nice easy read. I don’t think you need to have read her other books to enjoy this since it’s the beginning of everyone’s story but generally I recommend you read everything she writes.
Most of the books I write about are rated G but just so you know this is a little more grown up book. Regardless if you like the Fantasy genre I think she is a must read!
