What’s it about?
The story.
Dev and Boja's journey continues as the power of Flember becomes tied to wilder forces on the island. This fourth book broadens the emotional and geographical scope of the series, moving the heroes through a landscape where magic, nature and danger are increasingly connected. Jamie Smart's humour remains lively and cartoonish, but the series is now working with bigger fantasy stakes: who controls Flember, what the island needs, and whether Dev and Boja can help restore balance. The appeal is still highly visual, with full-page energy, expressive drawings and comic exchanges making the adventure easy to follow even when the plot becomes more layered. It is especially suitable for readers who have outgrown very short gag comics but still need illustration, humour and a warm friendship at the centre of their fantasy adventures.

In the classroom
How it works in school.
A funny, inventive fantasy-adventure series — a reluctant-reader-friendly classroom-library pick.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.
Why it lands
Why they love it.
Why kids love it
The specific shift is nature itself becoming the magic — the Wildening turning out to be wilder and more dangerous than anyone expected, Dev and Boja journeying through landscapes that match the bigger fantasy stakes. The penultimate Flember that sets up the finale.
- Adventure and freedom
- Having a secret base
- Making a difference
- Secret world
- Surviving danger
Why parents love it
The penultimate Flember — magic-and-nature tied together, the island's danger fully revealed, the arc accelerating into final-book territory. Best in sequence; the wider stakes only land if the earlier mythology is in place.
- Shared humour
- Beautiful illustrations
- Quick to read
