A Door Behind a Door by Yelena Moskovich
From Two Dollar Radio:
In Yelena Moskovich's spellbinding new novel, A Door Behind a Door, we meet Olga, who immigrates as part of the Soviet diaspora of ’91 to Milwaukee, Wisconsin. There she grows up and meets a girl and falls in love, beginning to believe that she can settle down. But a phone call from a bad man from her past brings to life a haunted childhood in an apartment building in the Soviet Union: an unexplained murder in her block, a supernatural stray dog, and the mystery of her beloved brother Moshe, who lost an eye and later vanished. We get pulled into Olga’s past as she puzzles her way through an underground Midwestern Russian mafia, in pursuit of a string of mathematical stabbings.
