A Rogue's Revenge — Valerie King

TO FIND TRUE LOVE...
When Sarah Kittling's family falls upon hard times, only an influx of money will sustain their position in Bath society.

She fears to imagine what the real Lord Gaventry thinks of his fictional portrayal...

But he never expects to fall in love with her...
