Joanna and her mother, Katherine, are rare female werewolves who can procreate without the mating bond specific to true-mates. They are highly prized by unmated males who want heirs, especially the powerful Alphas and Primes. When Jo meets Yuri and Vlad Volkov, twin Alphas of the Siberian Pack and her true-mates, she knows that she will not have to endure a lonely, stressful life on the run like her mother. The full moon is rapidly approaching, filling Jo with equal amounts of elation and fear. It is the only time werewolves are fertile and when they can form a true mating bond. Jo and her mates will become united forever, but Jo also knows that her mother is in great danger at this time. Who can she trust to help? Katherine waits in a secret, isolated location, but is it safe enough from a sadistic Prime who is desperate to find and enslave her? Will Jo be able to help her mother in time to begin her life with the men she loves? Note: There is no sexual relationship or touching for titillation between or among siblings.
