Thunderhead
A year after the events of Scythe, the perfect world overseen by the Thunderhead is quietly coming apart. Citra, now the compassionate junior scythe Anastasia, gleans with unusual mercy and earns admiration across the scythedom. Rowan has gone rogue, hunting down scythes he believes have betrayed their sacred calling. Watching over it all is the Thunderhead—the all-knowing, benevolent AI that governs every part of human life except the scythedom, which by ancient law it is forbidden to touch.
Into this uneasy balance steps Greyson Tolliver, an unremarkable young man whose fate becomes unexpectedly bound up with the Thunderhead itself. As a power struggle within the scythedom escalates and old enemies resurface, the fragile line between order and chaos begins to fail, testing everyone's faith that a machine—however wise and well-meaning—can truly keep humanity safe from itself.

This novel is the second installment in the Arc of a Scythe trilogy and relies heavily on the worldbuilding and character development established in the first book, Scythe, making it unsuitable as a starting point for new readers.
The narrative concludes with a significant cliffhanger that serves to bridge the events of the second book into the final installment of the trilogy.
While the previous book primarily alternated between the perspectives of the two main protagonists, this sequel expands the scope by incorporating a wider range of character voices, including the internal reflections of the artificial intelligence known as the Thunderhead.
