Honestly, some of the summary opinions I've skimmed talk so much about the octopus narrator, Marcellus, and his wisdom that they kinda gloss over Tova's whole journey. Her process of dealing with grief and that quiet, persistent loneliness is the actual backbone of the story. People get dazzled by a talking cephalopod—which, fair, it's a great hook—but Tova’s character shows how closure isn't always a big dramatic reveal; sometimes it's just cleaning a tank and letting someone new in. The summaries that click for me are the ones noting how her meticulous routines are both a cage and a lifeline. The book’s real magic isn’t in the mystery plot but in watching her stonewall emotional defenses slowly erode, not because she’s solved her son’s death, but because she’s finally, exhaustedly, ready to not be alone. Marcellus just gives the plot a nudge; Tova does the heavy lifting of changing her entire world at seventy-plus years old.
I also saw a few hot takes arguing that Cameron, the other human lead, is underdeveloped or just a vehicle for the plot. Those feel a bit harsh? His whole arc of fumbling toward responsibility and unpacking his own mother issues provides a messy, necessary contrast to Tova’s order. The summaries that dismiss him miss how his youthful self-absorption makes Tova’s hard-won wisdom shine brighter. They’re two halves of a conversation about belonging, just at opposite ends of life.
