SuperPower: The Ability to Fly or to Become Invisible: In Ashes, Phoenix Eagles Shall Rise (Book #4)

Despite the world's belief that Professor Steele has been terminated, a rumor of his resilience shines through, especially aggravated by his exterminator, Myrena Gorgona.
The Professor, with his two nephews, Apollo and Rocky, take a lunar transporter to the Moon where Professor Steele, using his technological genius, helps make technological advances at the Lunar Hilton, creating lunar lakes that support sea life and extracting valuable energy resources from the lunar surface.
Rocky and Apollo Steele, with the help of Robbie the robot, create the first Alan Shepard Apollo 14 Lunar Golf Course, which they play on several times; other days, the twins, with the lunar real estate mogul, explore to own property on the lunar surface.
After being back on Earth, Apollo Steele desires to marry Amelia Kristensen. Still, her father refuses unless the Steele twins can help his multimillion-dollar seafood corporation by completing 12 Herculean tasks. The twins' tasks are to defeat Leo Nemean, remove the nine heads of Hera Lernaean, catch and stop Hind Ceryneian, defeat the Erymanthius Boar, clean the stables, race Aries and his Stymphalian Birds, capture the Cretan Bull, capture the Night Mares of Diomedes, order a Gold Belt From Amazon Queen Hippolyta, get the stray herd of Geryon, obtain the golden apples of the Hesperides, and capture Three-Headed Hades Hound, Cerberus.
As the CEO of the Steele Corporation, Myrena Gorgona discovers that the single life isn't as grandiose as she thought. With the help of her BFF, Astrid Christiansen, she embarks on a thrilling journey into the world of Internet dating. Meeting several worthy suitors, she takes each one to worldwide fashion shows, where her designers and fashion team showcase their new lines. As each relationship fades, her fashion orders skyrocket, marking the excitement of her new experiences.
She discovers a photo of her exes, Rocky and Apollo Steele, next to an attractive, young relation whom she cannot detach from her thoughts. She needs to know who he is and why she must have him.
