The race is on to invent 'a device to further human understanding' and thus capture the fabulous DeWit Bequest. Enter the Existometer and its designer Hayden Sabanack, freelance scholar, and his assistant Sophie - she of the 'ungovernable urges'.
We are on the south coast of what was once England, in Brighton, the most highly charged of the city-states into which early 21st-century Europe has ionized. Though imbued with the spirit of freedom, Brighton has a menacing underside. Crooks and conspirators abound.
Can Hayden win through and crack the riddle of existence? Even with 'jizz' on his side, that is, a factor of potentially cosmic significance? And what of Francesca and Babette? Not to mention Sophie? Will several billion years of organic evolution find a fitting justification? Yes.
Jizz is a book of onslaughts, which is also that remarkable rarity, a comic novel of ideas. John Hart is the original new voice in contemporary fiction - lucid, saucy, significant. Above all, though, hugely enjoyable.
