A Billionaire Wolf for Christmas — Terry Spear

When the wolves' own blood betrays them, they risk their lives to find a miracle.

Wolf shifter Dr. Aidan Denali has been working day and night to find a cure for werewolves' alarmingly sudden decline in lifespan. The key to the problem eludes him. But when Aidan grudgingly leaves his work to do some holiday shopping, he meets a remarkable she-wolf whose mysterious pack could bring him one step closer to the answer.

Dr. Holly Gray is thrilled to meet the wolf who's been working so hard to help others. Now, it's her turn to help him. But while their attraction is sizzling, the packs are at odds, and the danger is increasing. It's going to take a holiday miracle for Holly and Aidan to get themselves--and their loved ones--out of this alive...
