Blurb: When Paul Sparks is dumped by Alison, he decides to use a gateway into a million parallel universes to look for a new girlfriend - an Alison who won't dump him. It's a simple plan - he's a simple man - except for the forces of the Random, a man called Joseph Kaye, and a cockroach that doesn't exist. Sci-fi comedy.
I know David Quantick primarily as the creator of the Blaggers Guide To... on the radio so when I heard he had a book I rushed out and downloaded it onto my kindle(1).
(1) Okay so I rushed out in a metaphorical sense.
