Billionaire Baby Dilemma (Billionaires and Babies, 54)

Family was everything. Control was everything else. So when Lucas Demarco discovered he shared custody of his orphaned niece, he was determined to change the situation at once. Especially since the baby's aunt, Devin Hartley, despised all the Demarcos. Yet he'd underestimated Devin's devotion. She believed he only wanted the baby as part of a family power play. But Lucas had their niece's best interest at heart. Convincing Devin of that fact wouldn't be easy. Especially when his desire for her was out of control - and about to turn them from enemies into lovers.
