Wearing the Cape book 8. Serious spoilers for the previous books.
Astra and the team are mostly relaxing. Shelly, lucky girl, is in a think tank meeting discussing how their ability to project the future when an attack begins by taking out Shell's connection. Meanwhile, Brian and Ozma are in Oz -- Ozma help deliver a baby -- only to receive news of the danger. They return to Chicago to a brutal, multi-faceted attack, leading to a lot of deaths.
The tale winds on from there. It involves a subplot about Kitsune and Astra; a wake several days before the funeral; Astra's disobeying an order; a hero telling someone to ensure his sidekick gets the cure if only one of them can; a new set up to get heroes into action; new discoveries about the Green Man; more geopolitics; and more. Significant changes.
