Entangled Publishing, 2016
From the publisher: Not Okay, Cupid launched on the Top 100 Bestselling Contemporary Teen Romance and has remained there. Readers are falling in love with Felix James–comparing him to Tim Riggins (our favorite FNL football player) and the book to teen classics 10 Things I Hate About You and She’s All That.

Now Hazel’s in free fall-until her best friend’s brother, Felix, gives her the perfect idea. Reclaim her power by taking revenge on her cheating ex.
