Wole Talabi is back. His second novel, The Fist of Memory, is a first-contact thriller that pairs Tope, a Nigerian assassin working for a witch doctor, with Itumeleng, a South African astronomer haunted by dreams, as an alien craft sets off a global crisis. DAW published it in the US on 27 October, Gollancz has the UK, and Masobe Books brings the West African edition on 16 November. After Shigidi took the Nommo and Ilube awards, this one is worth the wait.
