Cinderwild

The mermaid died. The witches burned. Godmother witches are meant to protect, but Marina failed them all.

The Thirty Years War draws closer to her home of Strasbourg, France, shrinking the Black Forest, the source of the witches' power. Out of options, Marina consoles herself with vodka and her lover, the bastard Kasimir.
When Marina discovers Cendrillon, a mistreated stepdaughter with raw magic, she apprentices the girl as a last resort. As Marina teaches Cendrillon to wield her power, they battle murderous witch hunters, evil stepsisters, and the ever present threat of war. But before Cendrillon finishes her training, Strasbourg is attacked, and Marina faces an impossible choice, save the last of the wild woods or protect the city and man she loves. What's worse is no matter Marina's choice, she could lose Cendrillon to the fire she fears most.
A reimagined fairy tale romance set in 17th-century France intertwines the Little Mermaid and Cinderella in a powerful tale of female friendship and second chance love.
