"Create a vibrant and captivating back cover for the book 'The Monkey Fortress.' The background should depict a lush green jungle scene with detailed illustrations. Include a mother monkey and a kid monkey playfully smiling and swinging from the trees. Center the composition with Marsha and Martha, the identical twin sisters who are the main characters. Marsha is cautious and curious, while Martha is fearless and brave. They stand close together, displaying their unbreakable bond. Surround them with elements that hint at a mystery adventure—hidden pathways, an ancient-looking map, and a partially obscured ancient fortress in the background. Incorporate playful and adventurous illustrations to create a visually appealing and thematic back cover that complements the front cover's jungle adventure concept. Ensure the illustration style matches the front cover to maintain consistency.
