Jenna Kingsley's new life in London with Aziraphale and soulmate Crowley is a beautiful dream until Hecate, Lucifer's executive assistant, warns her and ruler of Purgatory Vega of an impending darkness threatening to infiltrate their dimension. In response, Vega and Lord Beelzebub return powerful archangels Gabriel, Michael and Sandalphon, as well as demonic lords Hastur and Ligur, to their respective realms, thus suspending their Earthbound punishments indefinitely. This, however, is the least of Jenna's concerns: according to Hecate, the expert on everything interdimensional and dangerous, the dark force heading toward God's world is more powerful than Heaven and Hell combined. With the Almighty remaining as silent as ever in the face of universal annihilation, their only hope is uniting not just Heaven and Hell, but other mythological/mystical/magical forces across multiple dimensions to defeat the nefarious black entity planning to devour all they know.
Demon Princess Erish loves to spread chaos, but the war isn't entirely her fault. Disrupting the natural order to save her dying fiancé? Yeah, that's probably her fault.
But disrupting the natural order has consequences, and now no one is safe. To restore balance, Erish is exiled and brainwashed, both her freedom and sanity sacrificed to keep the worlds safe. From her.
But chaos can't be caged for long, and Erish has already broken the worlds once, she's willing to break them again to get her life back. The only problem is, the fiancé she sacrificed everything for... might be fighting for the other side.
