Hera couldn't care less what the other gods think, even when it's about her. And it often is. Frankly, Hera couldn't care less about anything, except doing her duty as queen - protecting order and defending the mortal world against any threats. But when the Fates go missing, Hera and a handful of other gods must temporarily become mortal to search the human world for the missing goddesses. Hera finds that mortality begins to change her. It's not just the loss of her divine powers. She expected that. It's deeper somehow. It's affecting how she thinks, how she feels, what's important to her. And it gets much worse after she meets Justin, who defies every prejudice she once had about mortals. At the worst possible time, and despite all her efforts, Hera's black-and-white world starts to unravel. Torn between who she's becoming and who she needs to be in order to fulfill her duty, Hera must survive a horde of murderous creatures sent to exploit her new weakness. In the end, only Hera can stop a traitorous plot conceived by a secret alliance of ancient and new enemies, a plot that threatens to destroy not only the order Hera is sworn to protect, but all of existence itself.

Athena is dead. Justin is gone. The Heavens have been cut off from the mortal world. Unwilling to risk their own lives, the other gods exile Hera to the mortal world to repair the damage. Alone and mortal once more, Hera must find a way to stop her most ancient and cunning enemy: Ekhidna, the Mother of All Monsters, who is bent on amassing an army to finally claim the mortal world as her own. But Hera can’t stop Ekhidna alone. She needs help. Mortal help. And so Hera begins a new mission: to seek out and awaken special mortals, mortals with the latent ability to wield divine power, mortals destined to become champions of the Heavens and guardians of Order. The Age of Heroes has returned.
