Descendant Machine

From the award-winning author comes a gripping, fast-paced and fascinating science fiction adventure. Vividly imagined and sharply written, fans of Ann Leckie and Becky Chambers will be engrossed.
The Grand Mechanism is a machine the size of Saturn's rings that has lain dormant for all recorded history, watched over by the alien Jzat. Now, rogue elements in Jzat and human society conspire to activate it, hoping it will bring them power and opportunity. But the only person who knows the Mechanism's secrets is the Rav'nah Abelisk, a Jzat holy man on sabbatical aboard a vast alien megaship. Believing the Mechanism's activation will bring galactic devastation, Nic Mafalda has to seek out the Abelisk before his sacred knowledge falls into the wrong hands — but only if she can first escape the lethally radioactive remains of her wrecked scout ship.
