Some Like It Hotter — Deb Stover

Abigail Kingsley can't believe it! Hasn't she been through enough deprivation and heartache in the wake of the Civil War? Now a big, handsome Yankee has appeared uninvited in her great hall, insisting he's from the future....

For Natchez detective Mike Faricy, this has been one helluva day. First his partner and best friend is killed in a shootout. Then a funny little man appears at precisely the moment Mike offers to sell his soul in exchange for his partner's life. Before Mike can blink, the man promises him the chance to relive June 19, 1997, the day before the killing, in order to change fate. Who could blame him for agreeing? But he should have read the small print. Now Mike is facing a knockout of a dame in Civil War-era dress who insists it is June 19... 1865!

A man out of time. A woman out of options. A devilishly charming love story. Add them all up and you get a match made in heaven!
