He's her husband, but he's not the man she married.
Caden and Greyson come home from deployment to build a life together. Everything is perfect, until Caden starts changing into a different man---one with a savage edge that's as dangerous as it is sexy.
Who is her husband?
What has he become?
And why?
Caden's roughness hits new heights, and so does Greyson's pleasure.
She's falling in love with a man she never married---a man whose very existence is a mystery, and one she's hell-bent on destroying.
With time running out and forces bigger than their marriage working against them, Greyson needs to put together the pieces before Caden takes it all too far…
