In this thrilling conclusion of The Deception Engine series, our heroes, the swashbuckling transgender/non-binary Phyllida Thorn, and their paramour, Hilary Templestowe, find themselves separated by strife and distance. Phyllida is in crisis, and Hilary, detained at their enemy Phineas' pleasure, hopes Phyllida will save her, and at the same time wants Phyllida to stay as far away as possible. IFLED Commandant Isabel Fuckard has plans of her own, and Phyllida's dastardly twin brother Phineas is still trying to take over the world (it's steampunk, dear reader - there must be a megalomaniacal villain, you understand).

Strap yourselves in to laugh, ugly-cry, and wish the whole world was as good a circus as the one in The Deception Engine Part 3.
