The lives of a young Jewish man in the 1930s and a young Czech woman in the 1980s echo across generations in Mansbach's (Angry Black White Boy
) continuing investigations into ethnic identity. Tristan Brodsky, the son of New York Jewish immigrant parents, is introduced to pre-WWII jazz and African-American culture by a City College professor who mentors him into a mostly successful, though often controversial, career as a novelist. Tristan's grandson and namesake, known as Tris, is a suburban teen in thrall to hip-hop culture who becomes a novelist himself. (Tris's writerly angst provides some of the funniest scenes in the book.) Then there's Nina Hricek, a talented young Czech photographer who is all but adopted by a touring American jazz group passing through Prague: the black band members affectionately dub her “Pigfoot†and insist that she must be part Creole. Nina becomes a sort of apprentice to the group's tour photographer. One night, when covering a gig at New York's Blue Note, she locks eyes with a man working at the club—Tris. Mansbach moves effortlessly between U.S. jazz clubs of different eras and Communist Prague, and his dialogue rings true. Believably eccentric characters and an inventive cross-generational plot make this novel of immigration's vicissitudes a delight. (Mar.)
