Simidele is one of the Mami Wata, mermaids who collect the souls of those who die at sea and bless their journeys home.

But when a boy is thrown overboard a ship of enslaved people, Simi saves his life, going against an ancient decree and bringing terrible danger to the Mami Wata. 

Now Simi must journey to the Supreme Creator to make amends - a journey of vengeful gods and treacherous lands. If she fails, she risks not just the fate of the Mami Wata and the boy she loves but also the world as she knows it. 

This is a story that will change history.
