Omega’s Vampire Bodyguard by Hawke Oakley

Forced to protect a human omega.
Adriel isn’t looking for love. He’d rather be writing his newest novel about vampires – a topic he’s intimately familiar with as an alpha vampire himself. Instead, he has to guard to a young human omega named Caleb, who is the target of the coven’s crazy matriarch. One wrong move and Caleb’s life will be lost – but Adriel isn’t going to let that happen.
Guarded by his vampire idol.
The last thing Caleb expected when he unwittingly walked into a den of vampires was to run into his favorite author of all time. Despite the unpleasant circumstances, Caleb is determined to make the most of the situation. After all, is there anything more romantic than being stuck in a cottage with your greatest hero?
But opposites don’t always attract. Caleb is Adriel’s number one fan, and although Adriel wants to keep him safe, he’s not interested in humans.
Especially when it involves creating a baby.
