She's Marjorie Finnegan. She's a temporal criminal. What more do you need to know? Oh, all right then: all Marj wants to do is race up and down the timelines, stealing every shiny-gleamy-pretty-sparkly she can lay her hands on. But her larcenous trail from the Big Bang to the Ninety-Fifth Reich has drawn the beady eye of the Temporal PD, whose number one Deputy Marshall is now hard on our heroine's tail - and taking things extremely personally. Worse still, Marj's worthless creep of an ex and his even scummier partner have seen an angle of their own in all this, and they intend to use her time-tech to change history for their own benefit. Marj's only ally? A guy called Tim. And he's just a head.
I mean, come on. What use is just a head...?
