Although this is a novel, it read more like a memoir. A woman loses her best friend and mentor to suicide, and she finds herself with his dog, a beautiful rescued harlequin Great Dane named Apollo. Her grief is mirrored by that of the dog who cannot understand the disappearance of his master. Nunez tells the story of their devotion, while providing passages containing research about suicide and grief, the dog in literature, as well as the teaching and writing life of the narrator and her mentor. I listened to this book in one long trip, and found it moving and beautiful.
