The Nanny by Fen Wilde

Melinda just wants a quiet life, with a stable job and some kids she can love. But a change in her circumstances finds her taking on a live-in nanny role in her thirties—not quite the life she had imagined for herself as a young woman.
Still, it’s the perfect place to start again. Or so she thinks, at first.
Her employer is a progressive stay-at-home dad who’s ready to return to the workforce, and he’s younger and hotter than any dad she’s ever encountered in all her years in childcare. Thrown together in such close proximity, Melinda keeps her lustful thoughts to herself, and devotes herself to her job.
But life is complicated. Why is James’s wife never home? And then there’s Melinda’s past, which isn’t staying where she left it. Throw a toddler into the mix, and will anyone in the house get their HEA? And is it ever really possible to get a second chance and start again?
