Isla Foster and Colin Jackman are strangers. Slaves to the daily grind of life, they each receive an anonymous invitation to a masquerade ball — one of the most prestigious events in New York City. There they are given lavish costumes, false identities and an opportunity to take part in a seductive game. If they accept, for one year they will meet in a series of secret rendezvouses designed to let them escape reality, consequence free. No one will ever find out where they go or what they do, as long as they follow three simple rules:

•  
• 1. they must never know the other’s identity
• 2. they must only meet at the prearranged times and places
• 3. they must not fall in love

What could possibly go wrong?
