The Empire’s richest city is about to revolt and only Jarrod’s dying father can save the day. The rebels have allied with ghosts. Hostile Northerners press at the borders, along with hideous beings of unnatural origin.

Jarrod doesn’t want to fight. He was supposed to be a monk, reading precious books, singing hymns to the wise and gentle gods of his people. But he’s about to discover something utterly horrific at the heart of the rebellion.

Another gripping sci-fi / fantasy crossover from Peadar Ó Guilín. The story unfolds very skillfully, step by step revealing the truth of the magic-tinged medieval world it is set in. And it does so at pace - this is a fast moving thriller that kept me turning the pages right to the end.
My only criticism is that the pacing is at the expense of detailed world building, but that's perhaps the price of keeping the plot wheels turning.
If you enjoy books by the likes of Dan Simmons, China Miéville, or the old 2000AD comic strips by Pat Mills and Alan Moore, you'll find something to love here. And if you've already read Ó Guilín's earlier books, you'll know what to expect - horrifically fascinating action with monsters, traps and surprises, and cowards and weaklings becoming strong heroes and vice versa.

A fascinating story that moves genres surprisingly yet internally the story hangs together very well and has a very satisfying resolution - highly recommended!

A sufficiently advanced technology is indistinguishable from magic, and a sufficiently advanced fallen civilisation is indistinguishable from fantasy. Jarrod is the sixteen year old son of the Empire's hardest and toughest general, who is sent by the Emperor to subdue a troublesome city in a northern province. So far, so sword-and-sorcery fantasy. As well as its natives, the city is also awash with ghosts, obviously human but equally obviously not just the spirits of dead locals. Thereafter the plot takes turn after turn in new and unexpected directions, overlapping from its starting point into far future science fiction with the fate of two worlds and all humanity at stake.

Jarrod is a born innocent; even his father recognised he was better off in a monastery, where he spent a couple of happy years before being wrenched back into the real world by the exigencies of palace politics. At first he can barely cope with the sheer nastiness he is thrust into, but he learns and manages. Just as you think the worst thing possible has happened to Jarrod, it turns out that something even nastier can happen to him. By the faintest possible of threads, he clings on to his humanity and integrity, and emerges the victor in a way that accommodates rather than triumphs over his adversities.

I thought that this was very good. The book starts with its young protagonist accompanying his father who is taking up a new post as the governor of a city whose inhabitants speak to ghosts. The people of that city have apparently gained knowledge from those ghosts which has made them pioneers in technology and science, but this has made their Emperor suspicious and jealous of the city's success. To begin with, this seems to be a novel of political intrigue, but it quickly becomes clear that there's a lot more going on than anybody initially realises. Having read Peadar's previous books I know he has an inventive imagination for vicious things to happen to his characters, and that is also on full display here. Although it's a fairly short book, there is a lot that happens in it, and it does all build to a satisfying conclusion although there are plot strands that could be picked up in a sequel.

I finished this at a canter in the small hours of the morning and hope to get a full review of the book up on the fantasy-hive in the next week or two.

My problem will be how to convey the intricately twisting surprises in the plot, and the many resonances with other books and films that Ó Guilín has woven into a story that is constantly entertaining and wonderfully paced. I did wonder, as the narrative thundered to the books end like a stampede of cattle, if this tale could be finished in a single book. There seemed to be just too much to resolve, too much peril for the protagonists to overcome. However, - as with his earlier YA book The Call - Ó Guilín manages to deliver a satisfyingly complete stand alone tale, while also leaving scope to take the characters and the world forward into new adventures.

I will also add, given my own interest in the theme of climate change in fiction, that I have long said that every new book will or should address our current climate crisis on some level. For example Matt Haigs The Midnight Library references climate change in some of the alternative lives his near-death experience protagonist explores. I was delighted to find that Ó Guilín managed to weave that theme into this book as well.

How to classify this one? It certainly starts like an epic fantasy with Jarrod, the bookish younger son of the Empire's most brtual general, being sent to subdue a rebellious city. It continues like a fanasty until he reaches the city where the weirdness creeps in with ghosts in the streets who are communicating scientific advances to the cityfolk. This should surprise no-one who has read Peadar's previous work. He has a dark and twisted imagination that takes stories in unexpected directions. Soon it becomes clear we are in a post-apocalyptic SF setting. It is to his credit that he pulls this off convincingly as the story darkens significantly to border on horror. The characterisation is smart, there could be more world-building but it would probably slow the tight pace.

My conclusion - this is high class Grimdark SF.

[Farah Mendlesohn]

One of the best YA writers in the business.

On one side the Empire, on the other a colony, and on yet another side people from a different planet. all desperate to survive.

Vivid, intense and, as always with Ó Guilín's work, ethical challenges.
