Dr. Accidental Daddy by Holly Rayner

He never wanted a family.
She never planned to fall for her neighbor.
One baby changes everything.

Dr. Jordan Hadley lives for his work, and keeps the rest of his life at arm’s length. But when a sudden tragedy leaves him caring for his infant nephew, and the carefully controlled world he’s built begins to unravel around him…
Alexa Costello is a single mom barely holding it together. Between job rejections, overdue bills, and a son who deserves more than she can give, the last thing she needs is a new job… especially one working for the brooding, irresistible doctor next door.
What starts as a temporary arrangement turns into late nights, shared laughter, and a makeshift family neither of them saw coming. But when fear, boundaries, and old wounds get in the way, Jordan must decide what matters more: his career, or the love growing right at home.
