In a last ditch effort to make the most of what Academy life has to offer, two students facing expulsion set off on a joyride to end all joyrides. In a borrowed shuttle, they reach Kallig, a doomed planet in the far reaches of the galaxy, and discover that Kallig's destruction is closer than the Curators had previously thought. In a race to save as many unique inhabitants as they can, the students and their specimens flee the reach of the unstable star before they are engulfed by the supernova that destroys their collected passengers' home planet.
Whilst en route to the holding planet, Errit, for safe deposit of the remaining Kallig, and staying just beyond the grasp of the authorities demanding the return the shuttle, a Mindcast protocol is accidentally initiated on a healthy specimen, a practice deemed illegal by The Academy.
Transmitted in real time, the Mindcast relays the recent thoughts and actions of Lin, a young Kalliga who over the previous days had searched to find how and why her childhood friend had been murdered.
Relayed by a soon-to-be ex-student, this story is written from a prison cell, on a tablet that would be wiser used for drafting a confession. What is ultimately recorded, however, is the history, the culture, the life and the way of the Kallig, a pre-industrial society rich in tradition, compassion, love and revenge.
In the epic conclusion to the Devil's Deal series, Freya has one final chance to discover the full potential of her own power, and to use it to restore balance in the universe - once and for all. After the destruction caused by Roisin, Ferya and Torix come to terms with their losses and mistakes... And prepare for a final battle that will change everything.
