Gaia. Personification of the Earth. Mother of giants, monsters, titans. A primordial goddess with a history of rebellion and destruction, and a woman with a stubborn desire to have all her children at her side. A revered goddess with powers beyond imagination, she has allies in low places, and access to the most off-limits areas—including the perilous Underworld jail. Gaia needs that access to free her imprisoned children and dethrone Zeus, once and for all. With the aid of dead soulmates, zombified humans, and mind-controlled gods, she aims to restore order to Earth before it consumes itself, overrun with political feuds, deadly climate changes, and human greed. Angry and determined, she's on a warpath to avenge her beloved offspring locked up centuries ago. Holding on to a grudge many thought buried, Gaia will stop at nothing until she's successful. Untouchable. Glorious. Is anyone strong enough to stop a deity so powerful she can create armies with a well-placed whisper? Who has the wits—and the nerve—to oppose an ancient and incredibly resourceful goddess such as Gaia?
