Boxer, Beetle be Ned Beauman. An extremely unique and fun read: In the present, a war memorabilia collector that smells like fish happens upon a past mystery involving a Nazi sympathizer/entomologist that becomes obsessed with a gay Jewish boxer.
"For the Relief of Unbearable Urges," by Nathan Englander. This book had an enormous impact on me. The idea that one could write Jewish stories with modern and critical sensibilities was incredibly liberating.
