"Smart, warm, uplifting, the story of an out-of-the-ordinary heroine whose deadpan weirdness and unconscious wit make for an irresistible journey as she realizes the only way to survive is to open her heart.

But everything changes when Eleanor meets Raymond, the bumbling and deeply unhygienic IT guy from her office. When she and Raymond together save Sammy, an elderly gentleman who has fallen on the sidewalk, the three become the kind of friends who rescue each other from the lives of isolation they have each been living.
