Kara was here

the long version

"Brad Mitchell's life is falling apart. Both his marriage and health are in limbo. The woman he thought he would marry, Kara, has died from an overdose. A friend keeps trying to convince him that Kara was actually murdered. And then there's Kara's ghost. She keeps visiting. Kara Was Here tells the story of a failed actress whose life and sudden death are only partially understood; her teenage sister, Gwen, who starts taking dangerous steps into Kara's secret world; Kara's college friend, Margot, who went from being the football team's sexy secret weapon to the solitary proprietress of a baked goods business; and Kara's one-time lover, Brad, who stands with one foot in the past and one foot in an increasingly uncertain future"--Author's web site.
