Soul Tourists by Bernardine Evaristo

Stanley Williams, angst-ridden banker and boffin, wonders whether there's more to life than his daily nine-to-five grind. One night he's dragged to a disco at Piccadilly Circus and there he meets Jessie: artiste, motormouth, ducker and diver. She swoops Stanley out of his soulless life and off on a rollercoaster road trip across Europe, bringing him face to face with a host of forgotten luminaries from the rich mix of black European history and literature.
