La tierra sin retorno

Frida, Miriam and the twins enter the dark kingdom of Alamantrah to rescue the missing dogs, there they rescue their beloved and special friend Iaso, the healer, the only person capable of curing Jericho of the poisoning he was a victim of. On the journey into the perpetual mist of Nevelhem, they will discover that the streets are divided and that their missions are becoming more dangerous every day. They will have to face new and chilling creatures; vampire animals, hypnotized rats and hungry ghosts. Their journeys on ghost ships through dark rivers will lead them to discover surprising cities and Petrademone's intrepid border collies will be at their side in the most decisive moments. But there are too many puzzles that have yet to be solved: who controls the worshipers of Shulu? Why has Miriam lost her voice, but at the same time she is able to prophesy the words that appear in the Book of Doors? Why does the Lord of Nightmares lock the souls of children behind mirrors? The boys will have to aim directly at the heart of the evil and deactivate it. Will they be able to do it without losing their souls?
