After the death of her husband, Tova Sullivan began working as a night cleaner at the local aquarium. The job helps her feel useful, especially in her loneliness after his death and her ongoing grief since her 18-year-old son disappeared 30 years ago. When she discovers that Marcellus, the giant Pacific octopus, has been escaping on nightly adventures, the two develop an unlikely camaraderie. When a young man shows up in town, Marcellus realizes he knows something about him, and Tova's past.

This bestselling novel from 2022 is absolutely delightful. Full of grief and hard things, yes, but Marcellus' voice is distinctive (and you MUST listen to the audio--the voice actor for him is so wonderful!). His observations about humans will have you chuckling, and his relationship with Tova will warm your heart. My only complaint is that we didn't get MORE Marcellus (his chapters are criminally short).
