The 'walking dead' have invaded a cemetery in Philadelphia and threaten the expensive World Exhibition and a beloved brother is missing in this YA horror tale. Young Eleanor needs to find her brother while avoiding the hordes of the dead. To do so she finds assistance from a scruffy group of misfits who use Steampunk-esque tools to fight the dead (and spirits too). The various mysteries are a bit light, but the action and horror is fun. The main heroine is feisty, and her love interest is intriguing and intelligent but the romance feels a bit one-note. Quick, easy, fun read. Hopefully the sequel will have a bit more meat.
