SOLVED. Slayer reverse harem

[Morgan]

I read this book with in the last few months, but I can’t remember what it’s called.
The book starts out with a girl (the main heroine) finding out she is a slayer, and the rest of her family was (mom,dad,Grandma). I think she finds out on her 18th birthday but I’m not positive. I don’t remember a ton of the midsection of the book but I know she is sent to an academy of some kind and begins to question here slayer lineage, when the creatures she is supposed to slay saves her. I think they might be fae, or maybe a mixture of various supernatural creatures, I’m not sure. She ends up falling for the guy that saved her, a little while later she is contacted by two or three other guys who need her help after the guy she fell for went missing. I know there was some kind of portal, that could only be entered with another creature from that realm. She went to the other realm and stayed with one of the guys who she also feel for, while they tried to find the first guys she feel for. I believe this all happened in one book but it may have been through out a series, but I don’t think so. I think the word Slayer was in the title of the book, but I’m not sure. I read this book I kindle unlimited if that helps.

Ending Spoilers

I know they enter her realm (earth) near the end after they find out the first guy she fell for is being held prisoner in the basement of the academy. They almost all escape but to save the guys she loves she stalls the students and teachers of the academy so they can get away and in the very end of the book she is stuck on earth and can’t get to the other realm.

I thin other main guys are Kong’s or leaders of their realm.
