Dark Continent:The Ministry of Unseen Affairs. Dark Continent Universe, #1

In the northern basin of Lake Malawi - the oldest freshwater lake on Earth - twelve million people are waiting. They have been waiting for three hundred and sixty-six years. When a Ministry researcher enters a catatonic state in Room Seven of the Ministry of Unseen Affairs, the signal he transmits carries seven impressions. The seventh is a name. The name belongs to Zola Banda - a field Adept with the widest Weave reception ever recorded, and a mother inside the lake.
What Zola finds beneath the surface will force the African Continental Authority to reckon with what its civilisation has been built on. It will take her inside contact with a man who died in 1681, falling from a ship's mast in the Atlantic - a man who has spent three and a half centuries organising twelve million Middle Passage dead while the outside world looked away. His name is Tomás de Souza.
He has three requirements. Dark Continent is a fourteen-book Afrofuturist epic set in near-future Africa, drawing on the oral traditions of the Malawian lake district, the Gule Wamkulu ancestral tradition, and the specific grief and grandeur of the African diaspora. For readers of N. K. Jemisin, Nnedi Ofofor, and Colson Whitehead.
