His Christmas Baby by Bella Lane

Shawna Jamison has always done what she wanted and never cared what anyone, including her mother, thought about her life choices. Her sister’s wedding should have been a joyous occasion, but for Shawna it turns out to be anything but, until he intervenes.
Jonathan Moore is Special Ops Forces, home on leave for his brother’s wedding. He’s instantly pulled to the blond beauty with the haunted eyes and fake smile. When he sees her doing shots, he never expected when he intervened for it to take a passionate turn.
In the morning the beauty is gone and all that’s left is a note. No names were exchanged, but neither one expected the lasting consequence of their night.
