The Shifter’s Wish by R. A. Boyd

Widow Cass Stephens wants to mourn in peace. A freak snowstorm, and the fear of no snacks, drives her out into the cold and into the arms of two sexy shifters who may or may not want to rob her of her can opener.
Jax and Damon have been cursed. They need Cass to complete their Alpha Triad and awaken the dormant beasts within them. And they really need that can opener.
Acceptance from their Clan is enough stress, but Cass’s presence brings unease to the surrounding packs and they’re willing to start a war to stop the Triad from forming. Cass will either prove she’s strong enough to be part of the most powerful Triad the shifter world has ever known or die at the hands of those who are afraid to find out.
