Serena's Web - 4R's, #3

Serena McClain's father has been kidnapped by the mob, and she's determined to rescue him. Except her only attempt fails when her PI is gunned down, and she barely escapes amidst a hail of bullets, thanks to FBI Agent Mark Riley. Forced to take her and her son into protective custody because of her meddling, Mark is not happy. He's more than a glorified babysitter. Still, he can't help being drawn to the feisty blonde and her cute kid.
They're evoking feelings in him he'd rather ignore. Even though agents promise to make finding her father a priority, Serena doesn't quite trust them, especially Mark, yet the more time they spend together, the deeper their connection grows. Will they find her father alive, and is real love worth the risk of Serena's Web?  Tropes: forced proximity, single mom, damsel in distress, protector, men in uniform
