Maybe in Missoula — Toni Volk

Annie announces she is giving up sex. Her husband, who runs a furniture store, is suitably appalled. Her decision sets in motion a quest to find her real place, her real home, maybe even her real love.
From her hometown of Butte, Montana where she grew up in the local bar her parents own, she takes her teenage son and heads for Idaho. But something stops her. Bound to the big skies and the crisp scent of the pines, they end up in Missoula, where Annie reconnects with her husband's brother Paul, her first love. There she examines her life - her passionate attachment to these two brothers, always in competition with each other and for Annie's affections.
