When the Decepticon Shockwave convinces the rogue Starscream to attack Sam Witwicky and his Autobot friend, Bumblebee, Optimus Prime and the rest of the Autobots try to help their friend, but the cost may be higher than they know.

Castor's fellow exorcist John Gittings made several calls asking for help before his untimely demise, and if Castor had answered them, his friend might still be alive. So when a smooth-talking lawyer comes out of nowhere to claim the corpse, Castor owes it to John's unhappy ghost and even more miserable widow to help out. But life is rarely that simply for Felix Castor.--From publisher's description.
