The Goldfish Boy
by Lisa Thompson
An anxious boy's surveillance notebook becomes the only witness when a toddler disappears next door — a tender, tightly crafted middle-grade mystery about OCD, grief, and the slow work of starting to heal.
The story
Twelve-year-old Matthew Corbin hasn't left his house in weeks. His OCD keeps him upstairs, scrubbing his hands and recording every neighbour's movement in a careful notebook. When the toddler next door vanishes in a single unobserved minute, Matthew realises his compulsive log may be the closest thing to a witness the police have. Alongside Melody Bird, the graveyard-loving girl from across the road, he works through a rotating list of suspects — while, quietly, the buried grief at the heart of his family begins to surface.
Age verdict
Best fit 10-12. Works for strong readers aged 9-13 with guidance for sensitive readers.
Our take
Literary craft book with adult-legible depth: parents and teachers will prize it higher than most kids do, though motivated middle-grade readers still find a real heart-punch mystery underneath.
What stands out
Each audience's top 3 dimensions. Out of 30 scored per book.
Kids love
- Heart-punch Exceptional
Three stacked emotional peaks in the final third — a private breaking-point scene, a long-buried family truth finally spoken aloud, and the resolution of the missing-toddler thread — each land hard because Thompson has been climbing that staircase for hundreds of pages. Similar to Bridge to Terabithia and Wonder for precision-per-tear.
- Character voice Strong
Matthew's first-person voice is one of the most distinctive in recent middle grade — count-obsessed, parenthetically digressive, deeply specific, similar to Wimpy Kid for voice distinctiveness but with Wonder-level craft. Melody's graveyard-enthusiasm and Dad's clipped three-word speech are also calibrated. Voice is the book's signature.
Parents love
- Emotional sophistication Exceptional
Three-stage slow-release of the buried-grief backstory across seventeen chapters, dramatic irony about a father's absence reading as rejection rather than love, and the refusal of a 'cured' ending all operate at the top of middle-grade emotional craft. Similar to Bridge to Terabithia for sophistication-per-page.
- Writing quality Strong
The writing is craft-forward without showing off — sentence length is calibrated to emotional state, the Wallpaper Lion destruction achieves near-poetic restraint, and the mermaid-gravestone scene delivers theme through imagery rather than statement. Similar to Wonder and The One and Only Ivan for literary care.
Teachers love
- Empathy & self-awareness Exceptional
Direct inside-access to a mental-illness narrative builds peer empathy that few middle-grade books achieve; the father's grief-driven absence builds empathy for adults with hidden pain; Melody's graveyard-love normalises unconventional grieving. Similar to Wonder and Out of My Mind for empathy construction; outperforms most issue-driven middle grade.
- Mentor text quality Strong
The first-chapter voice hook, the 12:55 p.m. blank page as absence-as-tension, and the stacked Wallpaper-Lion-destruction / mother's-confession sequence as emotional sequencing are all textbook teaching anchors. Similar to Hatchet and Holes for craft-instruction density.
✓ Perfect for
- • Thoughtful 10-12 year olds who love mysteries with real emotional weight
- • Kids who see themselves in anxious or detail-obsessed characters
- • Readers graduating from light mysteries who are ready for more depth
- • Families looking for an age-appropriate frame for mental-health conversations
- • Teachers seeking a mentor text for voice-driven first-person narration
Not ideal for
Very sensitive younger readers who find sustained anxiety upsetting, or kids seeking fast-paced action-per-page thrills. The backstory of an infant's death and the scenes of compulsive washing to the point of bleeding are emotionally heavy.
