She is cleaning cages and floors at Pope Pharmaceuticals when the President of the United States announces that human beings are no longer a viable species. When Zoe realizes that everyone she loves is disappearing, she starts running. Scared and alone in a shockingly changed world, she embarks on a remarkable journey of survival and redemption. Along the way, Zoe comes to see that humans are not defined by their genetic code, but rather by their actions and choices.

    What she finds is Urchin, the ragged and cocky crown prince of London’s mystical underworld. Urchin opens Beth’s eyes to the city she’s never truly seen-where vast spiders crawl telephone wires seeking voices to steal, railwraiths escape their tethers, and statues conceal an ancient priesthood robed in bronze.But it all teeters on the brink of destruction. Amid rumors that Urchin’s goddess mother will soon return from her 15-year exile, Reach, a malign god of urban decay, wants the young prince dead. Helping Urchin raise an alleyway army to reclaim his skyscraper throne, Beth soon forgets her old life. But when her best friend is captured, Beth must choose between this wondrous existence and the life she left behind.
