Plutonia

Russian writer and scientist Vladimir Afanasyevich Obruchev recreates a picture of our planet's distant past in his novel. The book's heroes undertake an incredible journey into the Earth's depths, where they will have to overcome many difficulties and dangers.
A group of brave explorers embarks on an expedition to the Arctic region, where they discover an amazing underground country, which they name Plutonia, inhabited by astonishing animals, insects, and plants that have long been extinct on the Earth's surface. Together with the book's characters, readers will encounter mammoths and saber-toothed tigers, see flying lizards and giant turtles, hunt huge dragonflies resembling mythical elves, and, of course, meet ancient human ancestors.
The illustrations by the famous artist Yuri Bogachev draw the reader into the mysterious world of Plutonia – a world where the sun shines day and night, giant ants live, and vultures of unseen size fly.
