Admirably unusual, and serves real purpose. Bonnello is writing the books that teenagers might relate to. GUARDIAN 

A singular achievement - a taut, thrilling, fully-rendered vision of dystopia. Bonnello's pacing and action will keep you on the edge of your seat. STEVE SILBERMAN, author of Neurotribes 

A fantastic twist on dystopia, with edge-of-your-seat thrills and unlikely heroes.. I loved it. MICHAEL GRANT, author of the Gone series

The Underdogs of Spitfire’s Rise are falling apart. A month on from their mission to destroy the AME shield, the surviving remnants of Britain’s last army are called into battle again – this time to avert the deaths of tens of thousands of prisoners. 

The Underdogs series, hailed as 'hugely popular' by The Guardian and much-loved within the neurodiversity community and beyond, continues into its penultimate novel. The war between the Oakenfold students and maniacal dictator Nicholas Grant is entering its closing stages, and the world is getting darker. Once again the neurodiverse skills and defiant bravery of the Underdogs are pitched against the horrors of military science… and, of course, innumerable cloned soldiers. Only this time, the battle against the mysterious Acceleration project will take place far away from New London, far away from home, and far away from anything Ewan and his allies have ever experienced before, physically or emotionally.  

Meanwhile, the teenage assassin 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. Conflicted after his conversation with Joseph McCormick, Roth sets out with five-hundred clones to find the Underdogs’ hideout, knowing that the mission’s outcome will define the young man he truly is. 

The Underdogs enter the next bout of their war against Nicholas Grant, clueless that their home is being targeted. Can Acceleration be stopped, with dwindling resources and fewer fighters than ever? What is Nicholas Grant’s endgame for Britain and the wider world? Will Oliver Roth find Spitfire’s Rise, and what will happen if he does?  

Underdogs: Acceleration takes an even more mature turn than its predecessors, discussing the darker elements of human nature, the emotional toll of leadership and combat, and building to a conclusion that will leave you pleading for book four’s epic finale. As always, the series remains suitable for both younger readers and adults, regardless of their understanding of special needs or neurodiversity. 

For those who have not already read the first two books, they can be found at https://chrisbonnello.com/ordering - or in the rewards panel on this page. 

For those who have, we hope you enjoy Acceleration just as much.

His first two Underdogs novels were crowdfunded through Unbound and was enthusiastically received by readers worldwide, especially in the special needs and disability communities. The second book has been shortlisted for the Guardian’s 'Not The Booker Prize'.

    Bonnello passed his master’s degree in Creative Writing with distinction, graduating in December 2017.

    11th January 2022 The final Underdogs book is now above 40% (but needs help)...

    Hi everyone,

    Well, feedback is coming in from those who have already read the Underdogs: Acceleration ebook (check your Unbound account if you’ve not seen it yet). I can’t say anything without running the risk of spoilers, but I’ll just say I’m delighted (and relieved) at how positive it is. Thanks to all who have contacted me about it, typically through Underdogs’ Facebook page.

    For everyone…

    Hi everyone,

    Underdogs: Uprising – the fourth and final book in the series – is soon to be open for pre-order, and the launch date I’ve been given is November 22nd (next Monday).


    I won’t clog up your emails with much information beyond that, not least because I want to avoid giving spoilers for Underdogs: Acceleration (with the ebook…

    10th March 2021 Stretch goals (and related bonus content to come)!

    So Underdogs: Acceleration is moving ahead, and the structural edit phase is about to begin. By mid-April that'll be done and it'll be time for copyediting. But the most relevant point for all of you being this:

    Those who pre-order the book will receive it about six months before the rest of the world. (So thanks a lot to all of you who brought it to life- this in itself is a pretty amazing reward…
