Keeping Faith by Beverley Oakley

Revenge is sweet until it breaks your heart.
Four years ago, Faith’s mysterious benefactress falsely accused her of stealing and deposited her in Madame Chambon’s exclusive brothel.
There, Faith was to learn how to entrance London’s noble gentlemen with her learning in philosophy, politics and art.
Her body was to be saved for the greatest enticement of all: revenge.
Faith doesn’t care what she has to do. She lives only to fulfil a bargain that will set her free.
But when Faith is recruited as the muse of a talented, sensitive painter whose victory in a prestigious art competition turns them both into celebrities overnight, she discovers the reasons behind her mission are very different from what she’d been led to believe.
Now she is complicit in something dark and dangerous while riches, adulation and freedom are hers for the taking.
But what value are these if her heart has become a slave to the man she is required to destroy?
