I am looking for a book where the female hero is kinda depressed about life. I think she recently had a breakup or so, so she was unhappy with the contemporary male species. She gave a weird Chinese cat doll I think a belly rub and is transported to the future. Once arriving there, she firstly finds herself captive of some kind of aliens and later on was found to not be a spy.
Earth is at war, I just cannot remember whether it was with some other country or some alien invader, or both. I do know that she is an empath and this is somehow supposed to help stop the war somehow. She falls in love with a humanoid lion alien and there is lots of kinky sex. Also, throughout the book the lion temporarily loses his memory of her because of his father, who is against their relationship.
I cannot exactly remember when I read the book, but it's been some years. I also know that it is several years old, so nothing new. Definitely 7 years or so. I also forgot whether or not it was part of a series or stand-alone novel. The cover I think has a lion head on it, and the title might be something about warriors of some weird sounded planet/alliance.
