This delightfully good-humoured novel is the sort of genre scramble that doesn’t often work: there’s a bit of 1990s family saga, a bit of mobster crime thriller, a bit of Cold War goat-staring spy story and really quite a lot of psychic/psycho-kinetic fantasy. And yet Daryl Gregory, who won several impressive prizes a few years ago for his fabulous horror novella We Are All Completely Fine, pulls the whole thing off with the unflustered charm of a stage magician.
