The Sea Beach Line by Ben Nadler
After being expelled from Oberlin for hallucinogenic drug use, Izzy Edel seeks out his estranged father—a Polish Jew turned Israeli soldier turned New York street vendor named Alojzy who is reported to be missing, possibly dead. To learn about Alojzy’s life and discover the truth behind his disappearance, Izzy takes over his father’s outdoor bookselling business and meets the hustlers, gangsters, and members of a religious sect who peopled his father’s world. He also falls in love.
As Izzy soon discovers, appearances can deceive; no one, not even his own father, is quite whom he seems to be. Vowing to prove himself equal to Alojzy’s legacy of fearlessness, Izzy plunges forward on a criminal enterprise that will bring him answers—at great personal cost.
