I need help for a gift!

I need to find a gift for a girlfriend of mine and i know she loves romance books but i dont read romance and i really have no clue what to get her. The only things i know are that: she read the "Love me Love me" series and loved it, her favorite book boyfriend is james from the same series but she didn't like his redemption arc, she preferred him troubled and a bad guy (i know, she got issues) and she loves smut. I looked at dark romance books but the reviews where all about how every one was bad written and like a wattpad story, please helpppp
