But don't take my word for it - here are some reviews:
'This story has it all - love, betrayal, blackmail, illicit love, scandal, secrets, danger, and savagery. And the list continues. Couple all this with the author's artful writing, and you have a novel that is sure to delight. I'm not surprised it is getting raving reviews already. The characters are so real, so believable, I'm still thinking of them hours after the story ended.' Great Historicals.

'A Dead Man's Debt is historical romance at its best. With this novel, you will find a poignant story about an untrusting woman, a notorious rake and the love that brings them both to their knees. This is a novel that should not be missed!' Lisa from 'The Romance Reviews'
