"Design a book cover for 'Journey Through the Unknown' by Siddheswar Mahanand. Set in a dense Amazon jungle, the background features lush greenery and an ancient, overgrown stone structure with intricate carvings. In the foreground, silhouettes of characters (Rohan, Maya, Anil, Zara, Dr. Neil) explore the ruins, exuding curiosity and adventure. The title, 'Journey Through the Unknown,' should be bold and prominent, with the author’s name below it. Use rich earthy tones and lighting effects to evoke a sense of mystery and exploration."
