Create an abstract, eye-catching book cover for "Heroes in Action

Create an abstract, eye-catching book cover for "Heroes in Action: Human Development Through Comic Book Characters." The cover should evoke a sense of action and human growth through abstract and artistic elements. Use a vibrant, contrasting color palette, including blue, red, green, gold, purple, and white. The style should be abstract, with geometric shapes, lines of energy, sparkles and lights. The background should be dynamic, using color gradients, lights and shadows to create depth and movement. The title "Heroes in Action" must be in a large, striking and modern font, centered on the cover. The subtitle "Human Development Through Comic Characters" must be just below the main title, in a complementary and legible font. Include the author's name at the bottom of the cover. Use abstract symbols that represent the characters' powers and abilities, such as energy lines for Doctor Strange or telepathic patterns for Professor X.
