Hanna Foster and the Guardians of Eden

Hanna Foster (almost 20), an American pickpocket drifting through Europe, is recruited to smuggle a mysterious box over the Alps. She thinks the box contains expensive rocks, but one of them hatches, and a strange creature emerges. It's a half-cat, half-lizard, and Hanna calls it "Trouble". It is a tatzelwurm. Hanna protects "Trouble", evades the black-clad men who try to stop her, and makes it onto the train that will take her through the mountains. But her adventure is far from over - one of her pursuers makes it onto the train and tracks her down. He knows something about the box and the creatures inside it - and about the creatures outside, high in the Alps. Before Hanna can sort out her situation, one of those Alpine monsters – a yeti – derails the train and sends it hurtling over a cliff. It dangles off the edge. Hanna climbs to safety, protecting “Trouble” and helping other passengers along the way. She finally confronts her pursuer, and learns that his purpose is hardly nefarious – the yetis are an invasive species, and the nearly extinct tatzelworm is their only natural predator. He’s after her to save the eggs (and the hatched creature) from the black market and return them to nature where they can fight off the yeti scourge. When Hanna and the remaining survivors reach the top of the cliff, they are attacked by a gigantic, furry beast – a yeti! “Trouble”, little as he is, tries to fight back! The little creature has no chance, but his tiny warbles are answered by a huge, flying cat-lizard. A rare, full-grown tatzelwurm flies in to the rescue! Hanna and her fellow passengers can escape! But the giant tatzelwurm isn't through with her. Hanna still has the box with the eggs. Hanna understands, and hands them over. When the eggs are in a strong mother's presence, they begin to hatch. A flock of tatzelwurms forms on the mountain. "Trouble" joins them, and Hanna makes her way back to civilization.
