Cry Wolf by Patricia Briggs is the first full length novel in the Alpha and Omega series but you definitely should read the novella, Alpha and Omega, first or it is a little confusing.
I have been devouring this series compulsively - it's just addictive and that starts with Cry Wolf! The more I read about Anna and Charles, the more I want to read. The people and events surrounding them are always interesting and often dramatic but never seem to go too far, in the sense that it never seems over the top or eye roll inducing.
The relationship between Anna and Charles is an interesting read because the two characters are so different and each have their own issues that need to be overcome. Charles is an alpha and an enforcer, not exactly an emotionally available guy, plus he's several hundred years old. Anna is in her twenties, has only been a werewolf for a few years, and was severely abused during that time. However, as an Omega, Anna is learning about her place and her power now that Charles has told her what she is. For his part, Charles wants to protect Anna but is trying hard not to smother her or scare her.
Add in Anna meeting the members of Charles' pack, a witch with evil plans, and a new werewolf haunting the mountains near the pack's home, and you get a novel with a fast paced plot and a lot of emotional turmoil. Cry Wolf has a little bit of everything - action, romance, plot twists, beautiful location, and fantastic characters.
I highly recommend the Alpha and Omega series by Briggs but definitely read the novella, Alpha and Omega, before reading Cry Wolf.
Anna never knew werewolves existed, until the night she survived a violent attack... and became one herself. After three years at the bottom of the pack, she'd learned to keep her head down and never, ever trust dominant males. Then Charles Cornick, the enforcer—and son—of the leader of the North American werewolves, came into her life.
Charles insists that not only is Anna his mate, but she is also a rare and valued Omega wolf. And it is Anna's inner strength and calming presence that will prove invaluable as she and Charles go on the hunt in search of a rogue werewolf—a creature bound in magic so dark that it could threaten all of the pack.
