Nurse Caressa Klein returns home to a quieter life in Vancouver, Canada, after five grueling years of working with patients in Africa. She’s ready to settle back into her relationship with her two best friends.

Engineer Michael Dubois has been in love with his best friend since the day she announced her departure overseas. He’s glad she’s back—now he wants to hold on to her forever.

Actor Cole Hamilton is also in love with his best friend. Or rather, both of them. They supported each other through harrowing childhoods. Cole wants to bring Caressa and Michael into his life and, more importantly, into his bed.

Can they move from friends to a throuple, or is their relationship destined to fail?
