Alpha Instinct (Moon Shifter #1)

Ana Cordona has been a strong leader for the lupine shifters who survived after all the males and most of the females in her pack were mysteriously poisoned. As tough as she is, with no Alpha male, the pack is vulnerable to the devious shifter Sean Taggart, who wants to claim both their ranch and Ana as his own. When Connor Armstrong comes back into her life, promising protection, it's almost enough to make Ana forget how he walked out on her before--and reluctantly accept his offer to mate.
The minute Connor sees Ana again, it reawakens a raw hunger. He must have her for his bondmate--his wolf cries out for it. But his human side knows he must proceed with caution because of their complicated past. If he is to truly have her body and soul, he must go beyond his burning desire and win back her heart. Whatever it takes, he is determined not to leave her side again. But Taggart and his rival pack are not their only enemies. A human element in town is targeting shifters. Their plan not only threatens Ana and Connor's future, but the lives of the entire pack...
