My books

“Admirably unusual”
“Serves real purpose.”
“Written with furious energy.”
“Bonnello is writing the books that teenagers might relate to.”
The Guardian

In addition to my work as an autism advocate, I have published several books (fiction and non-fiction). Here are my works to date.


The Underdogs series

A neurodivergent dystopia series, featuring a diverse case from a special school as front-and-centre heroes. The first three chapters of book one can be found here.


Unbound, 2019

One million cloned soldiers. A nation imprisoned. A group of neurodiverse rebels fighting back.

Britain as we know it lies destroyed. The hope of a trapped nation lies in a tiny number of freedom fighters hidden in the abandoned countryside – most of whom are teenagers who escaped the attack on their special school.

Seen by many as no more than misfits and ‘problem children’, this band of fighters could never have imagined the responsibility that now rests on their shoulders. After a lifetime of being defined by their weaknesses, the teenagers must learn how to play to their strengths, and become the best they can be in a world that has never been on their side.

A fantastic twist on dystopia, with edge-of-your-seat thrills and unlikely heroes in a well-realized world.  A fun, interesting book.  I loved it.
Michael Grant, author of the Gone series


Underdogs: Tooth and Nail

Unbound, 2020

Autism. Dyslexia. Anxiety. A millions cloned enemies. The Underdogs have returned.

Three weeks have passed since the events of Underdogs. The British population continues their imprisonment in Nicholas Grant’s giant walled Citadels, under the watchful eye of innumerable cloned soldiers. The heroes of Oakenfold Special School remain their last chance of freedom.

As a result of their last mission, Grant has been forced to speed up his plans for Great Britain and beyond. Ewan, Kate, McCormick and the rest of the Underdogs must face the horrors of his new research, knowing that it raises the stakes as high as they will go. Failing this battle will not merely result in losing soldiers and friends, but in losing the war entirely.

According to the odds, the Underdogs are near-certain to fail. But they have spent their whole lives being underestimated, and did not survive this long by respecting the odds.

Underdogs: Acceleration

Unbound, 2022

War is raging. Numbers are dwindling. It’s a dangerous world for an Underdog.

The Underdogs of Spitfire’s Rise are falling apart. In the series’ penultimate novel, the remnants of Britain’s last army are called into battle again – this time to avert the violent deaths of tens of thousands of prisoners. The neurodiverse skills and defiant bravery of the Underdogs are pitched against the might of military science, and the terrifying Acceleration project.

Meanwhile, Oliver Roth has been offered a promotion that would make him the second most powerful person in Britain. But it’s conditional on the success of his next mission… the discovery and annihilation of Spitfire’s Rise.

The Underdogs fight for the safety of countless prisoners, clueless that their home is being hunted. As each side launches their respective attacks, it’s only a matter of time until one side triumphs decisively over the other.

“This filmic, page-turning, edge-of-the-seat dystopian masterpiece does exactly what its title suggests—propel the reader straight into the action. Ambitious, brutal and brilliant: Bonnello’s best book yet.”
-Patience Agbabi, author of the Leap Cycle series, Fellow of the Royal Society of Literature


Underdogs: Uprising

Unbound, 2024

It’s the last days of the war. Humankind hangs in the balance. The stage is set for the Underdogs’ final battle.

After thirteen months of vicious warfare, the fight between the surviving Underdogs and the forces of Nicholas Grant is almost at an end. And everything in the world is at stake.

Beaten down but not destroyed, the neurodiverse heroes of Spitfire’s Rise have fought a war to be proud of. Thanks to their sacrifices, Grant is finally in a position where he could theoretically be defeated – but only if the Underdogs strike quickly and with everything left in them, and overcome the odds which have been against them since day one.

The remains of the Underdogs and the remains of Grant’s empire engage in a cataclysmic showdown, not knowing what the country – or the wider world – will look like once the dust settles around the survivors. The only certainty is that the final night of the war will decide the fate of the human population.

“A singular achievement – a taut, thrilling, fully-rendered vision of dystopia that teaches valuable lessons about the contributions that people with atypical minds can make when given the chance. Bonnello’s pacing and action will keep you on the edge of your seat.”
-Steve Silberman, author of NeuroTribes: The Legacy of Autism and How to Think Smarter About People Who Think Differently
