Three weeks have passed since the events of Underdogs. The British population continues its 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.

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 triumphs decisively over the other.

One million cloned soldiers. A nation imprisoned. A group of neurodiverse rebels fighting back. Britain as we know it lies destroyed. In the aftermath of the most daring military coup in history, the surviving population is crammed inside giant Citadels, watched over by an army of cloned soldiers. The hope of a 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. But perhaps this war needs a different kind of hero. 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.
