With the beginning of spring, the three elves Zirbel, Nießerich and Schlucker also wake up in their house under the old oak. Nießerich and Schlucker decide to build a boat and set off in search of their brother Wolkennase, who set out long ago to find the silver source. Thus begins the journey up the river, which leads them through the dark crow forest, where they encounter the Great Grum. Only with the help of numerous friends and a good portion of courage do they survive the journey and finally reach their happy home before the winter can get to them. Beautifully illustrated by Daniela Drescher Hardcover, 175 pages.
