Mush by Kathleen Bryson

'Mush' follows the progress of a sexual and emotional relationship between three Alaskan women. When Nicky and Carol meet Ellen in Seattle, the three women share an initially warm attachment. But the triad disintegrates as linked memories of the Alaskan wilderness turn simultaneously erotic and horrific...A haunting and lyrical first novel, Mush examines childhood ties and the dynamics of a menage a trois, and weaves dreams and myths into a modern setting. It's like Margaret Atwood on acid.
