The Nanny is Off Limits by Q. B. Tyler

Rowan Kincaid hasn’t dated in over a year.
Not since the mother of his children unexpectedly passed away leaving him to parent their three children alone.
Exhausted, overworked and feeling like he’s failing at every turn he’s desperate for help.
The help that shows up?
A gorgeous woman almost twenty years younger than him.
She’s compassionate and charming and the kids fall for her instantly.
And despite the fact that she should be off limits,
he falls for her too.
