This is the third book, and possibly the last, in A Conquered Earth series. This series has a very complex world and has multiple story lines going on at the same time so it would be best to start this series at the first book to understand all the issues and dimensions. This is also a very violent series with lots of fights, deaths and manipulations. Most of the characters are under 20, though they seem older than that in many instances. Those couple that are older seem to gather young people together for their own agendas and purposes. However, it’s not all gloomy. There is a wonderful touch of comradery between the characters and caring feelings that come out when they are least expected. The unity that the groups obtain does come at a cost but once formed, again it is wonderful. There is even a few touches of romance but it never goes past a kiss or two. This is a great continuation of this series and while it could continue this would also be a good stopping point. If I had to compare this to any book that I’ve previously read, I’d have to say this book has a Lord of the Flies flavor.
Holt and Mira have to go after Zoey who has been taken by the Assembly. They aren’t sure how they are going to rescue her but they have to try. To help them in their quest, they turn to the Wind Traders and the Menagerie. Both groups pose a major risk but if the survivors of Earth don’t unite, they’re never going to continue.
The sci-fi tour de force series concludes as the characters try and unite Earth’s disparate survivors to overthrow its alien invaders once and for all.
Earth has been conquered by an alien race known as the Assembly. The human adult population is gone, having succumbed to the Tone—a powerful, telepathic super-signal broadcast across the planet that reduces them to a state of complete subservience once they reach their early twenties. Which means that there is one group left to resist: Children. In Valley of Fires the trio of heroes -Holt, Mira, and Zoey- are forced apart to accomplish individual quests if they are to have any hope of uniting what remains of Earth's disparate survivors against its alien invaders.
Mira ventures west to bargain with Van Cleef, the enigmatic leader of North America's most infamous resistance group. But Van Cleef has his own plans to end the conflict, a destructive solution that might actually work...but at a horrible cost. Meanwhile, Holt travels with Ravan and Avril back to the one place he swore he would never return: Faust, the sprawling and dangerous desert city of the Menagerie pirate guild. He goes not only to resolve his issues with Tiberius, its tyrannical leader, but to enlist the Menagerie in the fight to save Zoey. Except Tiberius has his own problems. Factions within the Menagerie are splintering, and word of rebellion is beginning to spread. If Holt wants the Menagerie's help, he might have to help his greatest enemy in exchange.
Traveling separate paths with little hope of safety or reunion, Holt and Mira bring this thrilling, genre-bending series to an utterly unforgettable close.
