A Courtesan Countess Worth the Scandal by Ava MacAdams

A woman with a scandalous story to tell…

Popular courtesan by trade and avenger by choice, Nora Black knows all the juicy details that the noblemen of London want to keep hidden forever. When her family is threatened, she does the one thing she can to protect them: publishes a book exposing them all.
After his disaster of a marriage, Liam Westwood, the Earl of Keswick, made a sacred pact: never fall in love again. Having spent his years abroad, he never expected to meet a vixen that would test his sanity and haunt his nights upon his return.
With the Ton’s most scandalous secrets hiding between the pages of her book, Nora has no shortage of people who wish to see her suffer. And some are determined to see her ruined. When the manuscript falls in Liam’s hands, his feelings of betrayal are overshadowed by a single thing: a name that jumps out more than all the others put together. His.
