It's time to take down a demon.  The demon that's come to destroy this world has finally done it, he's broken Kari. But not in the way he hoped for. She's angry, ready to fight, and has every intention of taking him down once and for all.  With Kari's family growing with each friend she makes, she's surrounded by people willing to fight alongside her, for her. Tavionna's seething and ready to kill for Kari, Vahru's sick of threats, and Willa's been pushed beyond her limits.  The Nobodies have found the answers, the final battle is looming, but their plans have holes.
They don't have all the information, they don't have full access, and they risk getting caught before landing a surprise attack.  Will they succeed together in freeing this world from the manipulation and destruction of the demon or will they die trying?  *This is the final installment of the Among the Cosmos series and must be read in order.
