Hi guys! I k ow i dont have like any followers but im hoping you might be able to help! I'm looking for a book I read but unfortunately lost, I believe it's about a werewolf king and her sister is promised to him but it turns out she is his mate and true mates are very rare and there is some kind of curse on his family but it's not actually a curse but really just a guy that was close to him poisoning him but they eventually have kids and stuff, so idk if you could help but it would be much appreciated!!
