Shotgun Daddy by Harper Allen

A father’s duty.

Former hostage negotiator Gabe Riggs wanted nothing to do with spoiled socialite Caro Moore, the ice princess who’d left him high and dry after one night of fiery passion. But a year later, she came begging for the rugged Navajo specialist’s help — to protect her and her baby girl from a madman bent on revenge.

Telling Gabe the truth about his daughter would only put him in danger, and Caro couldn’t handle anyone else suffering because of her. But living under Gabe’s close guard at the Double B Ranch was threatening to expose the heart-stopping truth — that he was a daddy...and the only man she ever loved.
