After making and losing a fortune, computer whiz Alex has finally got his life under control. Alongside millions of others: as lead programmer for a company who looks after electronic gravestones, he knows just how lively the dead can be.
One of them is his mother-in-law, who emails out of the blue one day with a personal revelation that leaves him in the doghouse. But something's not quite right... an understatement that does no justice whatsoever to what happens next.
Big company politics, the dangers of weaponised custard, some mild cat peril, an inordinate fondness for beetles and a chase from Islington to geosynchronous orbit are just some of the ways that Alex's life goes from bad to worse to bone-shatteringly dangerous in this rather British take on what happens when cyberspace gets taken over by the elderly.
They're not in the mood for cocoa.
