Book Review: Attack on Planet Falrus by Joanna Monigatti

When an author hands you a world that feels both utterly new and warmly familiar, you sit up. Attack on Planet Falrus hooked us with that exact combination: bright, adventurous kids, a pinch of school-day mischief, and an escalating sci-fi threat that quickly widens into planetary stakes.

This is a children’s/young-middle-grade sci-fi adventure that wears its heart — and its worldbuilding — on its sleeve. The book reads like a classic kids’ adventure updated with modern science-y imagination and political tension.

What the book is about (spoiler-light summary)

The story opens with Giren Demba — an ordinary boy with a mischievous streak — who, with his twin Gomi and best friend Square (a child genius), discovers a strange, magnetized object on the Lokho Hills.

That discovery triggers a chain of events: mysterious projections, a broken mirror that shows a uniformed soldier, and the involvement of Falrus’s scientific community.

Dr. Buk Demba (Giren’s father) is a lead scientist in “Operation Animal Kingdom,” and soon the whole planet is on alert after nucleomagnetic readings reveal activity just outside Line Desimak — the boundary between Falrus and the so-called OLD World.

From there the book expands: robot allies (Professor Potty), secret exchange programs, hypnotized impostors, an authoritarian regime bent on conquest, daring child-led missions, and a genuine sense of peril for an entire world.

Characters who make the story work

What stands out is how the cast is built to balance kid-level relatability with adult-level stakes.

• Giren Demba — the narrator/protagonist; brave, slightly impulsive, and very human. His interior voice gives the book warmth and humor.
• Square/Tawam Takenan — the brilliant, gadget-loving friend whose inventions (and robot Professor Potty) drive much of the plot’s imaginative solutions. Square’s technical know-how is a delight and the kind of character kids love to root for.
• Buk Demba — Giren’s father, scientist and steady adult anchor who faces impossible choices as national security collides with family. His professional weight lends the story real tension.
• Kefra and Professor Potty — secondary but memorable; Kefra’s resourcefulness and Professor Potty’s role as a protector/engine of action add stakes and emotional beats.
• Commander Bonzok & The President — villains with an oddly bureaucratic, chilling bent; their scheme to harvest children as intelligence assets gives the antagonists an unsettling realism.

The cast is broad (scientists, families, military figures, and swapped/brainwashed children), but the novel keeps focus by returning often to Giren’s perspective and friendships, which makes the larger political plot feel grounded.

Themes & tone

At its heart the novel explores a few clear, kid-appropriate themes: courage, loyalty among friends, the ethics of science, and how ordinary people respond to extraordinary danger. Two themes stood out:

1. Child agency in adult crises — adults are competent but often sidelined; the kids’ resourcefulness becomes the narrative engine. The book embraces that classic children’s-adventure logic (kids can and will save the day) while giving the kids believable tools — brains, science, and teamwork.
2. Science: wonder vs. responsibility — nucleomagnetic tech and interplanetary transportrons create wonder and moral complexity. Scientists in the story are both heroes and figures whose work has unintended dangers; that ambivalence gives depth.

Tonewise the book moves between lighthearted kid banter and tense action scenes; Joanna Monigatti manages those swings mostly well, keeping the pacing brisk without losing emotional stakes.

What felt strong (and where it stumbles)

Worldbuilding is a strength: the galaxy, Line Desimak, Falrusian customs (Yoda’s Palace!), and tech ideas (HEST, quantoscopes, nucleomagnetic waves) are imaginative and consistently rendered. Repeated motifs (the Lokho Hills, the kitchen/household details) help the reader feel placed in the world quickly.

Where the book occasionally struggles is in information density. New technology terms pile up, and political machinations (exchange programs, district swaps, hypnotism) are sometimes explained in chunks that can feel expositional — necessary, but heavy for the target middle-grade reader.

In places the stakes ratchet fast and the narrative pauses for technical explanation; younger or less patient readers may skim those sections.

What we loved most (and one suggestion)

We loved the book’s sense of adventure and its emotional core — Giren’s friendships, his family, and the way the children’s curiosity and courage lead to solutions adults overlook. Professor Potty and Square are particularly fun: a flying robot + child inventor combo equals entertaining set pieces and clever rescues.

Our suggestion: a small appendix or glossary for the tech terms (HEST, quantoscope, nucleomagnetic concepts) would help reluctant readers and educators. A map of Falrus or an illustrated character page would also add welcome visual anchors for young readers.

Final verdict — who should read this

If you run a classroom library, are curating middle-grade sci-fi for kids who love A Wrinkle in Time energy mixed with Artemis Fowl gadgets, or want a family read-aloud with a mix of humor and high stakes, this is a solid pick.

It’s clever, imaginative, and anchored by likable kids who don’t feel like cutouts. The pacing and technical density keeps it from being a flawless five-star for us, but it’s an entertaining, earnest, and brave piece of children’s sci-fi.

Final score: 4.0 / 5 — imaginative, brave, and full of heart – for ages ~9–13, or adventurous younger readers with an adult.
