Tim Anderson final balanced rock stack in the Llano River. Tim Anderson, rock balancing “pro” from Pennsylvania, carefully worked to balance his stack on a dry spot in the Llano river Saturday March 12, 2016. He was an honored guest of the festival and enjoyed visiting Texas so he came for another year. The river was higher this year because of the rains so the balancers could not get to the better rock that were available last year. (Photo by Nell Carroll/American-Statesman)

Figurines of former pro-Russian separatist commander Igor Strelkov from the collection entitled “Toy Soldiers of Novorossiya” are on display at a workshop in Moscow August 29, 2014. A Moscow-based maker of toy soldiers has sought inspiration for his creations from Ukrainian rebels fighting government troops in the east of Ukraine. Toy soldier maker, Timur Zamilov, displayed his new collection of rebel fighters cast in metal on Friday, before they are due to go on sale. His new collection is entitled “Toy Soldiers of Novorossiya” (New Russia), a reference to regions in eastern Ukraine where pro-Russian separatist fighters want full independence. Zamilov's selection includes models of Cossack soldiers, volunteers, soldiers bearing anti-aircraft missiles and even a miniature of prominent rebel leader Igor Strelkov.

For more than three years, Ukraine has been plagued by a conflict between the eastern secessionist territories and the Kiev government. Demonstrations by pro-Russian parties that oppose the current government first began in 2014 - and now, over 10,000 people have died, many of them civilians. These images portray a generation caught between war and peace. Many of them were born into the civil conflict dominating the country and are disorientated about their place in the world.
