His third novel, Solo d'un revenant, was published in 2008, and won the Prix des cinq continents de la francophonie, and he followed that up with L'Ombre des choses Ă venir, published in 2009.
Efoui's plays were noted as having unclear settings, which were the subject of criticism as his works were considered too Western and too isolated from Africa, which Efoui did intentionally to link Africa and the West in his works.
Specifically, in Le carrefour, he described his characters as bodies, rather than specifically noting them as black or African.
