*An all-new steamy and angsty billionaire arranged marriage romance from the USA Today & Wall Street Journal bestselling author, Tracy Lorraine.

As the daughter of a powerful businessman, I wasn’t expecting to inherit much when my father suddenly passed.

There was only one thing I truly wanted.

The cottage— the only place that ever felt like home.

But it turns out that I got a lot more than I bargained for.

Kingston Callahan.

Arrogant, egotistical, power-hungry, demanding and all the other not-so-charming attributes I despised.

He’s also my brother’s best friend.

And now, thanks to my dearly departed father, my husband for the next year.

He’s everything I hate about the life I was born into. Everything I’m not.

One short year...three hundred and sixty-five days in return for the life I've always dreamed of.

It’s a merger, not a marriage, but I’m not prepared for the hunger Kingston uncovers with his touch.

It’ll all be over soon, just so long as I remember not to catch real feelings for my fake husband while we’re pretending.
