Mary and Bickerman are the center of their circle of friends--but these friends are strangers as well as family to them. In the course of year, under the influence of a stressful wedding and a whole lot of alcohol, relationships and nerves are twisted and broken as the dynamics of the cozy-seeming group shift. Secrets are kept, emotions withheld, and it doesn''t look like it''s going to end well for anyone.

Told always in first person, but not the same person, and unfolding in double-helix chronology that provides a Rashomon-like narration, Chum is the story of love, liquor, and death.
