The secret history of Moscow

Just released from a mental hospital, Galina, a young translator and recovering schizophrenic, doesn't quite believe her eyes when her pregnant sister abruptly gives birth and changes into a fleeing jackdaw. Yet others across the city witness similar transformations, including Yakov, a neighborhood detective assigned to investigate a disturbing epidemic of missing-person cases. When street artist Fyodor stumbles on a surprising clue to the avian mystery, Galina and Yakov follow him through a magic portal visible only in window reflections and into an underground world of forgotten misfits and mythical creatures.
