Sparks

"I will go back to reading David Quantick's excellent Sparks now" - Neil Gaiman

"If you choose to only live in one alternative reality make sure it's the one in which you read Sparks by David Quantick" – Ben Aaronovitch

When Paul Sparks is dumped by Alison, he decides to use a gateway into a million parallel universes to look for a new girfriend - 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.
