Prince Svetlova was so handsome, kind and sincere that even Lela herself, the goddess of spring, liked her. But a goddess cannot love like a mortal. On the first day of summer, she leaves her chosen one, and for almost a year, until the new spring, he has to wait to meet her. The groom, yearning for his beloved, becomes an instrument in the hands of Vela, the Mistress of Underground Water. From her, Svetlova will learn something that he would rather not know: how to keep Lelya on the ground so that spring does not give way to summer.
