Karma Girl. Bigtime, #1

Investigative reporter Carmen Cole gets the surprise of her life on her wedding day when she discovers that her fiancé and best friend are sleeping together-and that the two of them are her town's resident superhero and ubervillain. Shocked and hurt, Carmen reveals their secret identities and then decides to devote her life to unmasking every superhero and ubervillain who crosses her path. A series of successful unmaskings lands Carmen a job at The Exposé, one of the biggest newspapers in Bigtime, New York, a city that's full of superheroes and ubervillains.
Carmen is in her element-until she gets kidnapped by the Terrible Triad, Bigtime's most dangerous ubervillain team. The Triad orders Carmen to uncover the secret identity of Striker, the leader of the Fearless Five, Bigtime's most popular superhero team-or else they'll drop her in a vat of radioactive goo. With that threat hanging over her, Carmen sets out to unmask Striker, but what she doesn't count on is falling for the sexy superhero.
But with the Terrible Triad lurking around, this is one story that just might be the death of her....
