All those explosions were someone else's fault
(Book)

Monsters are real. But so are heroes. Sparks are champions of weird science. Boasting capes and costumes and amazing super-powers that only make sense if you don't think about them too hard, they fight an eternal battle for truth and justice . . . mostly. Darklings are creatures of myth and magic: ghosts, vampires, were-beasts, and the like. Their very presence warps reality. Doors creak at their approach. Cobwebs gather where they linger. Kim Lam is an ordinary college student until a freak scientific accident (what else?) transforms Kim and three housemates into Sparks-and drafts them into the never-ending war between the Light and Dark. They struggle to master their new abilities-and (of course) to design cool costumes and come up with great hero-names. Turns out that "accident" was just the first salvo in a Mad Genius's latest diabolical scheme. Now it's up to four newbie heroes to save the day, before they even have a chance to figure out what their team's name should be! -- from Amazon.
