Christina is a professor used to examining stories with a critical eye; until one day in middle age she finds herself falling in love and leaving her marriage for a romance with another woman. This involves a familiar enough tale, but when her new partner suffers a stroke, Tina begins to reflect on the sorts of love that novels rarely capture.

A heady mix of memoir, criticism and storytelling that draws on novels ranging from Pride and Prejudice to Price of Salt, Anna Karenina to Conversations with Friends, to illuminate the ways love and novels work, and show how some types of love, which don't race to a narrative end-point, might be the most important of all.
