Karma Girl by Jennifer Estep
Carmen Cole is a reporter for a small-time newspaper in a Southern town until she catches her fiance and best friend in flagrante delicto on her wedding day. In their passion they let slip that they are also the town's resident superhero and supervillain and Carmen gets her revenge by unmasking them in the media, an act that immediately transforms her career.
Exposing the secret identities of superheros and villains becomes Carmen's calling. She knows she's truly hit the big time when she's hired by Expose, the biggest paper in Bigtime, New York. Unmasking Bigtime's Fearless Five and Terrible Triad and will be Carmen's most difficult job yet...
Karma Girl is a light, but engrossing read. It combines chick lit with comic-book-style super heroes in a very entertaining way. While some of the plot twists are pretty obvious to the reader early on, others are a bit more surprising.
This book could have easily been over-the-top, but is is grounded by Carmen's character, which is both sympathetic and down-to-earth.
