I'm a huge fan of Patricia Briggs! This novella is a great introduction to her Alpha & Omega series. This is not a must read before the series starts, but it should be. This story is how they met and what happens. Cry Wolf picks up right where this ends. This series is also a spin-off from the Mercedes Thompson series. Again I recommend that you read both series, but it's not a problem if you don't. I loved this book and series!
