Cate Glass's A Summoning of Demons marks the thrilling conclusion for the Chimera team, a ragtag crew who use their forbidden magic for the good of the kingdom.

Catagna has been shaken to its core.

The philosophists insist that a disastrous earthquake has been caused by an ancient monster imprisoned below the earth, who can only be freed with magic. In every street and market, the people of Catagna are railing against magic-users with a greater ferocity than ever before, and magic hunters are everywhere.

Meanwhile, Romy has been dreaming.

Every night, her dreams are increasingly vivid and disturbing. Every day, she struggles to understand the purpose of the Chimera's most recent assignment from the Shadow Lord.

As Romy and the others attempt to carry out their mission, they find themselves plunged into a mystery of corruption and murder, myth and magic, and a terrifying truth: the philosophists may have been right all along.
