Run for the Hills by Kevin Wilson
I am not generally a fan of Kevin Wilson (the weird book where the children spontaneously combust when agitated -Ick), but I took a chance on his new novel, which while still quirky, is enjoyable.
Madeline (Mad) is a thirty-two-year-old organic farmer who lives with her mother in a small town in Tennessee. Her father left them years ago. Things are going fine (maybe a little dull) until a khaki-clad man shows up in a ridiculous car and claims to be her half-brother Rueben (Rube). He is not the only one; Rube informs her that she has at least two more half-siblings. Their father abandoned Rube, then Mad, and then two more families like a game of abandonment dominoes.
Rube wants Mad to accompany him on a road trip to meet their other half-siblings, Pepper a college basketball player in Oklahoma and eleven-year-old Theron in Utah, with plans for all four to confront their father, rumored to be living in CA.
There is never any question that Mad will join him, and so the quest begins.
The novel is somewhat predictable, but the burgeoning sibling relationships are credible and entertaining. Finding the father was never really the point.
