Redhead by the Side of the Road: Anne Tyler

A perfect love story for imperfect people.
Micah Mortimer measures out his days running errands for work, maintaining an impeccable cleaning regime and going for runs (7:15, every morning). He is in a long-term relationship with his woman friend Cassia, but they live apart. His carefully calibrated life is regular, steady, balanced.
But then the order of things starts to tilt. Cassia is threatened with eviction, and when a teenager shows up at Micah`s door claiming to be his son, he is confronted with another surprise he seems poorly equipped to handle.
Can Micah, a man to whom those around him always seem just out of reach, find a way back to his perfectly imperfect love story?
