The publisher's description:

In this fast-paced, cinematic adventure, Catwoman learns that like anything else in life, loyalty has its price. Presumed dead and without any cash, Catwoman must find a way to make a quick score to set herself up in Gotham again. Learning of a train loaded with unmarked cash headed to Canada, the sultry cat burglar gathers some old friends and devises a plan. But when one of her former allies sells her out to the mob, Catwoman's simple train robbery becomes a desperate gambit for survival.
