On Heliconia, a planet orbiting binary suns, the Great Year lasts three thousand years of Earth time: human civilization rises in the spring, flourishes during the summer, and nearly dies out with the onset of winter, which lasts for many human generations. Spring is just coming and Helikonia is slowly waking up from the too long grip of frost. The tribes of the equatorial continent come out of the shelters in which they survived the adverse climate, decimated to a minimum, and once again begin to compete for supremacy over the planet with the wild creatures of the cold - phagors. And in one of his villages, Oldorand, they rediscover crafts, trade, agriculture, coins and new dimensions of human relations. The novel Helikonie - Jaro is the opening volume of the great Helikon Trilogy, a monumental saga that surpasses anything written so far by one of the greatest masters of imagination in the science fiction genre.
