The Absolution by Yrsa Sigurdardottir--This Icelandic noir is the last of a three-book series. Detective Hulgar and his motley crew, aided by child psychologist Freyja, investigate the murder of a teen. It turns out that bullying is the reason the grisly crime may have happened. Social media also plays a major role in spreading cruel messages. Is that enough to drive someone to kill? Very strong sense of place, with the isolation of Iceland setting the prevailing tone. The killer is numbering the victims; where will it end?
