The Secret of Holly

After Andrew Milling, Karrag's sworn enemy, disappeared, the boy's life did not become any calmer. A criminal appeared in the city, who commits a series of mysterious thefts. The police are puzzled: the thief gets into places where an ordinary... person cannot possibly enter. Karrag and his friends realize: perhaps the kidnapper is just like them and can turn into an animal or insect… But when Karrag discovered the thief's traces, he became seriously frightened: the evidence points to the fact that the criminal is his best friend Holly. Is it true? And what should Karrag do now? The third book in the "Children of the Forest" series. Winner of the prestigious literary prize Leipziger Lesekompass. Bestseller according to the German magazine Spiegel.
