Purge by Sofi Oksanen

Deep in an Estonian forest, two women, one young, one old, are hiding. Zara is a prostitute and a murderer, on the run from brutal captors - men who know how to punish a woman. Aliide offers refuge but not safety: she has her own criminal secrets - traitorous crimes of passion and revenge committed long ago, during the country's brutal Soviet years. Both women have survived lives of abuse. But this time their survival depends on revealing the one thing history has taught them to keep safely hidden: the truth. A haunting, intimate and gripping story of suspicion, betrayal and retribution against a backdrop of Soviet oppression and European war.
