A Billionaire For The Night — Sierra Rose

This is book 2.

Phoebe goes to New York City for a florist convention. She hopes to be inspired by beauty...but not by the breathtaking beauty of a one night stand with a Greek god. When she meets a mysterious stranger who says they shouldn't use their real names or identities, she is intrigued. She becomes Ruby, the shipping heiress, and he is a poor man from the wrong side of the tracks. They spend a glorious night together deep in role play, and then go their separate ways, never to see each other again.

But sometimes fate has other plans...

Who was the mysterious man she slept with?
