Step into Mysterious Realms

A purplish mystery yet majestic fantasy book cover. A woman stands gracefully in her priestess robes (deep purple gown with a hood). Mystical symbols and runes glow faintly around her. Behind her, a grand mysterious temple, partially surrounded by swirling mist. Title is "The Divine Siren", the word Siren should be bigger. And below "First Priestess of Mystery" as a subtitle.
