BirthControl. La Patron, Birth Series, #2

When you're the top wolf on the continent with the backing of the Goddess, how does an enemy topple your kingdom? By challenging you to a fight?  No. By changing the rules. After three hundred years of fighting and service to the Goddess, Silas Knight is the Patron, Alpha to the Alphas on the North American continent. As the top wolf, he fears little and has seen most things. But when he discovers someone or something has been quietly disturbing the natural order of things, he's surprised.
Certain human women can birth fully functioning wolves, and that's a major problem. Jasmine Bennett has no idea her deceased husband was a wolf shifter or that her twin sons are shifters. Her life changes when she rushes to her son's bedside after he's wounded in Afghanistan and returned stateside. Now her life's in danger because of her ability to give birth to a breed of beings she never knew existed.
After sending out a mating call which Silas answered, Jasmine's pregnant and depressed. Her life has spiraled out of control. Silas is angry that his first "litter of pups" are half breeds. A group of human breeders offers her a chance to leave Silas, offering a strange brand of protection. When a human breeder enters the compound using a weapon the wolves are helpless against, Silas and Jasmine understand the true meaning of Birth Control.
This is the second book in the La Patron series. Book one is BirthRight and should be read first for a better understanding of this book.
