My priority has always been serving my country as a Navy SEAL.

But then my world is turned upside down and suddenly I have an adorable toddler to look after.

I won't be doing it alone—my sister-in-law Sam has joint guardianship.

But playing house with this firecracker of a woman is anything but child's play. It's been hard enough to ignore the electric chemistry between us at family gatherings, and now we're living under the same roof.

Hell Week was easy in comparison to keeping my hands off her.

I can't get distracted by the sparks between us, but doing so may be my toughest mission yet.

When Sam's medical research work leads to growing threats against her, the safety of my new family is put in danger.

Now I'm ready to protect them—to protect what's mine, at any cost.
