Create a book back cover that continues the dark and mysterious medieval theme of the front cover. The scene is set in the courtyard of a castle at night, with the same stormy, cloud-covered sky seen on the front. The moonlight is faint, casting long, soft shadows across the cobblestone ground. In the foreground, there is a stone well with ivy creeping up its sides, and beside it, a small cluster of blue thistle flowers, their vibrant blue and violet hues standing out against the muted colors of the stone and greenery. The courtyard is framed by tall, weathered castle walls, with a large, wooden door slightly ajar, suggesting an invitation or a mystery beyond. The atmosphere is quiet and eerie, with a sense of something hidden or waiting to be discovered. The book’s synopsis is placed in the center, written in a clear, Gothic-style font that matches the front cover, with a simple medieval border around it to frame the text.

Avoid using bright, modern colors or overly cheerful tones that would disrupt the dark, medieval atmosphere. Do not include any characters, animals, or modern elements like cityscapes or technology that would break the period setting. The scene should not be overly dark to the point where details are lost, and the design should avoid clutter with too many elements. The font for the text should remain clear and elegant, avoiding overly ornate styles that could make the synopsis difficult to read. Stay away from overly fantastical elements that do not fit with the subtle, mysterious tone of the overall design.
