Jimmy Martin has a sore head. He’s used to smuggling illegal data in his headspace. But this is the first time it has started talking to him. The data claims to be a distinguished academic, author and civil rights activist. It also claims to be a bear. A bear named Honey. Jimmy has nothing against bioforms – he’s one himself, albeit one engineered out of human stock – and works with them everyday in Hell City, building the future, staking mankind’s claim to a new world: Mars. The problem is that humanity isn’t the only entity with designs on the Red Planet. Out in the airless desert there is another presence. A novel intelligence, elusive, unknowable and potentially lethal. And Honey is here to make contact with it, whether Jimmy likes it or not.
