After the death of her longtime friend and flatmate, retired British history teacher Julia Garnet does something completely out of character: She takes a six-month rental on a modest apartment in Venice. She befriends a young Italian boy and English twins who are restoring a fourteenth-century chapel. And she falls in love for the first time in her life with an art dealer named Carlo.

Juxtaposing Julia's journey of self-discovery with the apocryphal tale of Tobias and the Archangel Raphael, Miss Garnet's Angel tells a lyrical, incandescent story of love, loss, miracles, and redemption and of one woman's transformation and epiphany.
