The Professor’s Omega Manny by Lorelei M. Hart

Manny’s Mannies: Where parents find more than just childcare—they find everything.
For Carter, an alpha professor of omega studies, life comes crumbling down when two officers show up at his work with horrible news and three young children in tow. His widowed brother Joey was killed in a car accident, leaving his kids orphans. Carter immediately agrees to take them in, quickly realizing he’s in way over his head. He needs help—he needs Manny’s Mannies.
Omega Beckham was on track to become his family’s first lawyer—until his grandfather became ill and he dropped out to take care of him in his dying days. He took on a new, more feasible goal of becoming a nurse and started working as a TA. But then his employer gets arrested and he comes home to an eviction notice and discovers his roommate was stealing the rent money. Jobless and homeless, he needs a solution and fast—he needs Manny’s Mannies.
When Carter opens the door to greet his new manny, he’s shocked to see his one-night stand from years earlier—the one he could never forget. If the kids didn’t immediately love Beckham, Carter might’ve asked for a replacement. Now he has to repress his longing for the manny he once spent a magical night with.
If only it were that easy.
