Creed (Unfinished Heroes book #2) by Kristen Ashley!!
This is the second book in her “Unfinished Heroes” series (the first being “Knight“). Book #1 was a very popular book with many fellow readers, as it portrayed a super-alpha male and his much more submissive heroine. But Knight is not your usual hero. In fact the author considers these guys her “anti-heroes”.
And while I didn’t connect so much to Knight as I normally do with Kristen’s alphas, many readers did. He is certainly an alpha and then some. The whole bad-boy thing, plus some other… stuff. 😉
