When Leah meets Charlie in line at the grocery store, their attraction is immediate and intense. Charlie is older than Leah but lives with his parents, meets up with a friend at odd hours of the night, sleeps a lot and always seems to be coming down with something. He confesses that he's a recovering heroin addict, but he promises Leah that he's never going to use again. Still, Leah's friends and family are concerned. Even when Charlie's behavior becomes increasingly erratic, Leah can't help but feel that what exists between them is destined. I Could Live Here Forever, Halperin’s second book (after Something Wild) is about a woman's relationship with an addict, fraught with compassion and codependence, and her enduring search for love.
