Diaper Duty Vampire by R.E. Mullins

During the Civil War, Union soldier, John Alden took a musket ball to the gut. As he gasped his final breath, he was turned into a vampire and started life anew in Amber Heights, Missouri. For over one hundred and fifty years, he’s lived a rather solitary life as a vampire Enforcer.

Young single mother, Joann Clarkson, needs a job and fast. Hoping to be rehired, she returns to Dr. Michaela Blautsauger’s lab prepared to eat a hefty helping of humble pie. She comes to regret that decision when she’s taken hostage. Things look grim but she’ll never stop fighting to escape. Her son needs his mama.

As an Enforcer, John must hunt down the vampire who kidnapped Joann. In his search, John winds up babysitting her toddler Cody. Changing diapers might be worse than getting staked, but nothing compares to how he feels when both mother and child fall into danger again.
