Simi Prayed to the Gods once. Now she serves them as Mami Wata- a mermaide- collecting the souls fo those who die at sea and blessing their journey back home.
 
But when a living boy is thrown overboard, Simi does the unthinkable- she saves his life, going against an ancient decree. And punishment awaits those who dare to dey it.
 
To protect the other Mami Wata Simi must journey to the Supreme Creator to make amends. But all is not as it seems. There's a boy she rescued, who knows ore than he should. And something is shadowing Simi, something that would rather see her fail...
 
Danger lurks at every turn, and as Simi draws closer the must brave vengeful gods, treacherous lands, and legendary creatures. Because if she doesn't, then she risks not just the fate of all Mami Wata, but also the world as she knows it.
