The Flame of Olympus - Kate O'hearn

Thirteen-year-old Emily's life is transformed when Pegasus, the mythological winged horse, crashes onto the roof of her building during a New York City blackout and takes her to Olympus where she faces monsters, a corrupt governmental agency, and the quest to keep the Olympic flame burning. Illustrations. A young girl, a winged horse, and an Olympian war make for an adventurous start to an exciting trilogy. When Pegasus crashes onto a Manhattan roof during a terrible storm, thirteen-year-old Emily's life changes forever. Suddenly allied with a winged horse she'd always thought was mythical, Emily is thrust into the center of a fierce battle between the Roman gods and a terrifying race of multiarmed stone warriors called the Nirads. Emily must team up with a thief named Paelen, the goddess Diana, and a mortal boy named Joel in order to return Pegasus to Olympus and rescue the gods from a certain death.

Along the way, Emily and her companions will fight monsters, run from a government agency that is prepared to dissect Pegasus, and even fly above the Manhattan skyline--all as part of a quest to save Olympus before the Olympic flame burns out.
