Someone recommend me bad ass books plz thanks

Also I'm trying to find this book I read a long time ago. If anyone knows what it's called please tell me. It's a werewolf book with an immortal werewolf king that's been alive for centuries or millenia I dunno and his mate is a star that he fell in love with yeeears ago.  He loses her somehow and then they forget how they fell in love and after meeting again centuries later they fall inlove all over again under the pretence that they are mates (they are but ya there's more to it than that) remembering things a little at a time realising what their true identities are.

IF ANYONE HAS READ THIS PLEASE GOD HELP ME FIND THIS BOOK AGAIN
