One Lonely Night — Susan Kay Law

Passion to last a lifetime... Kieran McDermott had given up on love long ago. Now he traveled around the country as a hired gun, righting wrongs and making evil men pay for their cruel deeds. When he nearly froze to death during a sudden snowstorm in Redemption, Dakota Territories, Kieran never expected the lonely Margaret Thayer's kindness would comfort him so well. Margaret had lived alone for so long, she knew that any opportunity for romance and marriage was left far behind her. When a half-dead gunslinger stumbled to her door, she took him in, never dreaming of the fiery passion he'd ignite in her. For a lifetime of memories she would risk one night. For a chance to hope she would risk everything...

Note: Kieran was first introduced in Home Fires.
