In Love with Her Secret Protector by Kate Hunt

A fiercely protective hero. A thrill-seeking heroine. Kept apart—and forced together.
Five years ago, I made a vow to my best friend that I would watch over his daughter after he was gone.
He also made me promise to keep my distance.
Better for everyone if she doesn’t know, he said.
And so, ever since, I’ve been Leila’s secret protector.
At the slightest whiff of danger, I step in and keep her safe. A never-ending responsibility, given the girl.
But the hardest part hasn’t been keeping Leila safe.
The hardest part has been keeping myself sane while falling in love.
I’ve tried and tried to rid myself of this infatuation, but it’s only gotten worse.
Leila is my everything, my heart’s desire, my one and only.
And she’s the one woman I’ve sworn to stay away from.
I won’t break that promise.
Not now. Not ever.
