Shifter Reverse Harem

[Melanie]

I'm lookin for a book where a woman meets her mate who is a large cat of some kind and ends up finding out that she is also the mate of his roommates. She comes from a well off family and has a bodyguard, a wolf I believe, who she is friends with and who also ends up as one of her mates. It takes her awhile to accept him because she finds out that he had previously slept with her stepmother whom she does not like and whom doesn't like her either. Eventually her other mates convince her to give him a chance. Also i think the mate she first meets is like the leader of their group. I would like to say this book came out between 2000-2015.
