The Alpha's Regret - Shifters of Grey Ridge, #4

Nathan is a playboy bachelor, living his life to the fullest. Being the brother of the Alpha has its perks, and Nathan makes the most of all of them. He's not looking for his mate. From what he's seen, they're nothing but trouble and heartache. Or that's what he thinks until his fated mate walks into the packhouse and turns his life upside down. Now he wants love, family, and a happily ever after.
The only problem is going to be convincing her. And the longer it takes him, the more danger she's in. Someone still has it in for the Grey Ridge pack, and the unmarked mate of the Alpha's brother could be an easy target.
