Divine intervention isn't all it's cracked up to be.
Gabriel didn't expect his return to Heaven to be filled with trumpets and celebration, but he thought he would do more than sit at Michael's side, listening to endless catalogs of unfulfilled prayers. He's tried blending into every aspect of Heavenly life, but he can't help but feel that the constantly praying Faithful and flower-dispensing Handmaidens lack the motivation to do any true good in the world. Some days, he longs for nothing more than to return to Earth and tell his beloved Cassia how he feels about her.
When Heaven is suddenly attacked, all the angels become trapped in their own nightmares. With Michael gone on an angelic mission, Gabriel must rally the remaining seraphim to rouse the sleeping angels and discover who seeks to take the agents of Heaven out of the celestial battle. All fingers point to Bedlam, but Gabriel can't believe the ex-demon would threaten his salvation so soon after gaining it.
With few people he trusts, Gabriel must rely on all the lessons he learned on Earth to save Heaven, Bedlam, and maybe even himself.
