Anne Tyler - Redhead by the side of the road
Micah Mortimer is a creature of habit. A self-employed tech expert, superintendent of his Baltimore apartment building seems content leading a steady, circumscribed life. But one day his routines are blown apart when his woman friend tells him she's facing eviction, and a teenager shows up at Micah's door claiming to be his son.
These surprises, and the ways they throw Micah's meticulously organized life off-kilter, risk changing him forever.
