I never expected my stepfather to become my roommate.

Daniel Walker has been part of my life since I was ten.

For twelve years, he was simply the man I called my stepdad—the man who attended my graduation, supported my dreams, and treated me like the daughter he never had.

Then I turned twenty-one.

My mother left for Europe.

And Daniel moved into my penthouse.

Suddenly, I was seeing the man behind the role I had always known.

The powerful businessman came home exhausted and barefoot.

The man who always wore expensive suits started wandering around the kitchen at midnight in nothing but sweatpants.

The stepfather who once lectured me about boys started watching every man who looked my way.

And the closer we became, the harder it became to remember that we were supposed to be family.

Then Ethan moved into the penthouse next door.

He was young.

Single.

Available.

And determined to have me.

Daniel hated him from the beginning.

At first, I thought it was because Daniel was protective.

Then I realized the truth.

He wasn't acting like my stepfather.

He was acting like a man who was terrified another man might take away the woman he wanted.

I should have walked away.

Instead, I pushed him.

I tested him.

And eventually, behind the locked doors of our penthouse, we crossed a line neither of us could uncross.

Now we're living a double life.

In public, he's my stepfather.

Behind closed doors, he's the man I can't stop craving.

But our six months alone are almost over.

My mother is coming home.

And someone has discovered our secret.

Soon, the entire world will know what happened behind our penthouse doors.

And when the truth comes out, I will have to choose between the family I was born into...

And the forbidden man I was never supposed to love.
