We all have break points to face - at the gym, in the office, in our personal lives - those moments of self-doubt where we have to dig deep, and find something within to grab hold of and push us through. Ex-Special Forces soldier Ollie Ollerton has faced his own break points and now he tells us the lessons he has learnt along the way. From survivor of a freak childhood attack to elite fighter, Ollie's incredible story features, high-speed shoot-outs, counter-terrorism and humanitarian heroics.

Ross Edgley famously ran a marathon pulling a 1.4-tonne car and climbed a rope the height of Everest (8,848m), after living with Yamabushi warrior monks in Japan and partaking in Shamanic pain rituals with fire ants in the Amazon jungle. On his epic 1,780-mile journey around Great Britain, which lasted 157 days, Ross swam through giant jellyfish, arctic storms, ‘haunted’ whirlpools and polluted shipping lanes, going so hard, and so fast, his tongue fell apart. 

Jason Fox served with the SBS for over a decade, thriving on the close bonds of the Special Forces brotherhood and the ‘death or glory’ nature of their missions. Battle Scars tells the story of his career as an elite operator, from the gunfights, hostage rescues, daring escapes and heroic endeavours that defined his service to a battle of a very different kind: the psychological devastation of combat that ultimately forced him to leave the military and the hard reality of what takes place in the mind of a man once a career of imagined invincibility has come to an end.

A jaw-dropping account of life as a prison officer in one of the country's most notorious jails. Neil ‘Sam’ Samworth spent 11 years working as a prison officer in HMP Manchester, aka Strangeways. A tough Yorkshireman with a soft heart, Sam had to deal with it all - gangsters and gangbangers, terrorists and psychopaths, addicts and the mentally ill. Men who should not be locked up and men who should never be let out. Strangeways is a shocking and at times darkly funny account of life in a high-security prison. 

In the boot were six homemade pipe bombs, all linked to detonate at the same time from a single call on a brand-new pay-as-you-go phone found on the target. Special Branch also found Chinese Type 56 assault rifles with eight full magazines of ammunition. His target was a local school. He planned to attack two coaches of teenagers returning home after a school trip to France. Approximately 60 children, their accompanying teachers and their waiting parents. He was going to kill them all.

It takes a tough mind-set to be a successful sniper, to be able to dig in for days on your own as you wait for your target, to stay calm on a battlefield when you yourself have become the target the enemy most wants to take out. Craig Harrison has what it takes, and in November 2009 in Afghanistan, under intense pressure, he saved the lives of his comrades with the longest confirmed sniper kill - 2,475 metres, the length of 25 football pitches.
