Wild and Wicked Things by Francesca May

A Sunday Times Bestseller and TikTok sensation
 
In the aftermath of the First World War, a young woman gets swept into a glittering world filled with illicit magic, romance, blood debts and murder in this lush and decadent debut novel. On Crow Island, people whispered, real magic lurked just below the surface. But Annie Mason never expected her enigmatic new neighbour to be a witch.

When she witnesses a confrontation between her best friend Bea and the infamous Emmeline Delacroix at one of Emmeline's extravagantly illicit parties, Annie is drawn into a glittering, haunted world. A world where magic can buy what money cannot; a world where the consequence of a forbidden blood bargain might be death.
