Absent-minded professor Malcolm Downey has just invented the sure thing that will lead to the academic easy street of tenure: a computer that can register human emotions.

Set in the world's most dangerous maximum-security penitentiary, home to the most treacherous criminals, tensions among the inmates and staff heighten, leading to anarchy that engulfs the prison and order is turned upside down.

Gray and Sam are brother and sister and best friends, flatmates in New York City, where she creates ad campaigns and he's a surgery intern. Their social life is too insular, so they head to a dog park so Sam can, maybe, meet a woman. He does - Charlie - a zoologist new in the city; he likes her immediately, and the feeling seems mutual. As the three of them spend time together, what if Gray's feelings for Charlie aren't just sisterly? Not only might this explain her solitary life, but it could lead to real dilemmas - with Charlie (who's sweet, but a bit opaque) and with Sam. No advice comes from Gray's therapist, but a co-worker and a cab driver give theirs. Can Gray sort things out?
