It was the afternoon of 18 August 1966, hot, humid with grey monsoonal skies. D Company, 6RAR were four kilometres east of their Nui Dat base, on patrol in a rubber plantation not far from the abandoned village of Long Tan. A day after their base had suffered a mortar strike, they were looking for Viet Cong soldiers. Then—just when they were least expecting—they found them. Under withering fire, some Diggers perished, some were grievously wounded, the rest fought on, as they remained under sustained attack. For hours these men fought for their lives against the enemy onslaught.

Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you're not a rich tourist or an eccentric billionaire. So smuggling in the occasional harmless bit of contraband barely counts, right? Not when you've got debts to pay and your job as a porter barely covers the rent.

Anthony 'Harry' Moffitt spent more than 20 years in the SAS. His decades of service and his multiple tours in East Timor, Iraq and Afghanistan made him one of the regiment's most experienced and recognised figures. Alongside the SAS, Harry's other lifetime love is cricket. An improvised game of cricket was often the circuit-breaker Harry and his team needed after the tension of operations. He began a tradition of organising matches wherever he was sent.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

April 2004: Dan Mills and his platoon of snipers flew into Southern Iraq, part of an infantry battalion sent to win hearts and minds. They were soon fighting for their lives. Back home we were told they were peacekeeping. But there was no peace to keep. Because within days of arriving in theatre, Mills and his men were caught up in the longest, most sustained firefight British troops had faced for over 50 years.

More than two centuries after World War III poisoned the planet, the final bastion of humanity lives on massive airships circling the globe in search of a habitable area to call home. Aging and outdated, most of the ships plummeted back to Earth long ago. The only thing keeping the two surviving lifeboats in the sky are Hell Divers - men and women who risk their lives by skydiving to the surface to scavenge for parts the ships desperately need.
