I just . . . I just love her covers and that's all there is to it. Chain Reactionis the third and final book in Simone Elkeles' Perfect Chemisty trilogy and will feature Luis--the youngest Fuentes brother. Given my enjoyment of the first two, I'll definitely be picking this one up when it comes out on May 24th. I'm thinking I kind of need to have the full set on my shelves.
