Sokotra - Ostrov dračí krve a temných jeskyní (2026)

This richly illustrated photographic travel book reveals the secrets of the isolated Socotra archipelago in the northwestern Indian Ocean, a place visited relatively rarely by Europeans. While most visitors admire Socotra’s endemic nature on the surface, traveler Michal Hejna and his colleagues Markéta Jakovenko and Martin Novák repeatedly headed in the opposite direction—down beneath the island’s surface. During three caving expeditions, the Czech explorers spent almost two months on Socotra and take readers to places rarely visited: its hidden, little-explored underground world. Socotra is an isolated archipelago in the northwestern Indian Ocean, about 350 km south of the Arabian Peninsula, and forms part of Yemen. The main island of Socotra is approximately 130 km long and up to 35 km wide. Around 50,000–60,000 people live there, mainly in coastal towns, with about half of them in the capital, Hadibo. Its long isolation has allowed many endemic plant and animal species to develop, earning Socotra the nickname “the Galápagos of the Indian Ocean.” In 2008, it was added to the UNESCO World Heritage List. The contents are in Czech.
