Aiden Aslin joined the Ukrainian marines in 2018, compelled to defend his adopted homeland from the growing threat of Russian invasion. In February 2022, as Russia mounted a full-scale offensive, Aiden and his unit were stationed at the frontline at Mariupol. Pinned down at a Mariupol steelworks, after a month-long siege and running out of supplies, Aiden was part of the mass surrender of over a thousand Ukrainian troops, in April 2022. Then his real ordeal began. Singled out for his British passport, Aiden was interrogated, tortured, stabbed, turned into a propaganda zombie, tried by a kangaroo court and then sentenced to death. A victim of a catalogue of abuses of international law, Aiden struggled to cling on to any hope of survival. Certain that he was going to be executed, he was eventually freed in a prisoner exchange and permitted to return home. In Putin´s Prisoner, Aiden will tell the full, harrowing story of his time fighting in Putin´s war, of his six months in Russian captivity, and of his hardened resolve to defend the freedoms of the people of Ukraine.
