Reckless Heart by Brighton Walsh

Turns out the gorgeous stranger I had a one-night stand with is not only my sister’s best friend but also my new employee.
Worse? I shared a whole lot more with Avery than one mind-blowing night.
I told her my deepest, darkest secret.
Despite my constant worry that she’ll let the truth slip to my family, I can’t stay away from her. And when we’re tossed together for an out of town trip and forced to share a room with only one bed, the chemistry between us finally explodes…again.
I have no problem making her see stars—or breaking the bed. The trouble is, the longer our secret relationship goes on, the more I want to keep her.
But she’s eight years my junior, the sunshine to my grump, and I know her free spirit wants more than the small town of Starlight Cove can offer.
I have no doubt no one will ever give her more pleasure than I will, but I refuse to hold her back.
Even if that means letting her go when her three month contract is up.
