“RETURN TO THE DARK VALLEY is contemporary literature at its urgent best. Gamboa's imagination - seemingly endless - fuses the horrors of terrorism, social class in Columbia and the life of Rimbaud amidst a cast of characters that linger in your head hours after turning the last page. With prose that pulsates with the rhythms of global cities, the reader sees a world of shifting latitudes and migrating populations. Bold, propulsive and generous, Gamboa's name should be mentioned alongside the most exciting Latin American writers ever published in English.”
