Tancredi is born on the same day that scientists discover a small planet they jokingly call Surprise. A planet so insignificant that it went unnoticed for millennia reveals, on closer inspection, that it will develop into supernova and is destined to be the instrument of Armageddon across the Universe.

Made rich by his invention of the MoronOmeter, Tancredi decides to make it his mission to save the world and buys a ticket on a space ship making its maiden voyage to the stars.

Beautifully illustrated and reminiscent of Gulliver's Travels and The Little Prince, Tancredi is in turn shocking and profound, undercut with the dark humour that made Tomas so scandalous and successful.
