After a lifetime of moving and change, Jan Carroll wants nothing more than to settle down and build a home. Then her father gets sick, and the stable—if solitary—life she’s made as a high school geometry teacher in Spokane, Washington, threatens to crumble around her. She wants little to do with newcomer Tina Nelson, a shallow and unreliable playgirl. Especially since their mutual friend Brooke Stanton has been not-so-subtly matchmaking…

Tina, a graphic artist and musician, has vowed to spend her life free from the obligations that characterized her youth. No ties, no long-term commitments. But she agrees to travel to Spokane to help her cousin promote his business and, in a second moment of weakness, promises to contact Jan. Tina is certain her acquaintance with the too-logical and inflexible woman will be a short one.

Sometimes, though, love makes you throw away life’s careful script. Can these women learn to improvise?
