A Lady Out of Time — Caroline Hanson

Sent back in time to Victorian England to stop the invention of a deadly weapon, Helen Foster knows the job looks too easy: All she has to do is go to an auction, buy the weapon plans, destroy them, and she'll save millions of people back in her own time. And even if she spends the rest of her life as a spinster stuck in the English countryside with a plethora of cats, changing the future is worth it.

Then she meets Edward Clifton, Duke of Somervale, the man she's supposed to blackmail. He is one of the most powerful men in the land, so handsome and cold that debutantes have been known to faint in his presence. After one meeting, Helen will be thrilled to never see his royal (and quite spectacular) backside, ever again.

But as her mission falls apart and danger closes in, Helen has no choice but to turn to the one man powerful enough to help her not just change the future, but survive the night.

This is the first of two books in Helen's series. The concluding book, A Lady Most Dangerous is available now! Please be aware that the swearing is pervasive, the sexual tension blistering and the historical details have not been taken too seriously.
