Joshua Hannes, the concierge of the Vivaldi Central Park Hotel prides himself on fulfilling every impossible request. Tickets to a sold-out show? A purple dye job for a purse dog? A last-minute table at a premier hotspot? No problem.

But the penthouse guest wants what?

Self-made billionaire Craig Ridley's in New York on business, but at the end of the day, he wants to relax with someone interesting. The concierge should be able to supply an entertaining companion. Just for a little conversation. Dinner and a card game, not sex.

Craig didn't expect the concierge to personally volunteer to be a rental friend, and he really didn't expect to get attached. How can a paid service ever turn real?

A billion reasons why they shouldn't be together. A billion and one reasons why they should.
