About the book: year / Kriol is a planet divided into two equal hemispheres by wind flow. Kriolians living on opposite sides of the air wall do not have the opportunity to overcome the barrier. The Veresens and Gurens have lived for centuries as separated, separate races, but there is something that unites them. Navi are girls worth fighting for and giving your life for. Once a year, the barrier disappears, revealing the Side of Reverse Rain, and at this moment such different peoples unite into one to restore the balance of life on the planet. The Navi girl Getta Sen-li-Keil becomes a hostage of ancient rules and customs. Her soul protests against centuries-old laws, but one chance meeting radically changes her worldview..
