As soon as I finished Worldshaker, I was more than eager to get my hands on Liberator. The story picks up three months after the revolution and the Filthies took control over the renamed juggernaut. Though they accomplished their goal, things for Riff and Col isn’t what they hoped. Tension is rife on the Liberator, with Filthies distrusting of the remaining ‘Swanks’, extremist Filthies pushing for more power and someone intent to bring the whole moving mountain to its knees.

The action is tenser than in Worldshaker, with things kicking off right from the beginning. Col can feel the distance between himself and Riff growing, and sensing the mounting unease on the juggernaut. As a previously unknown Filthy moves into the Revolution Council, and whispers in Riff’s eager, Col can’t help but realise the Filthies are being manipulated into making an already shaky situation into a full blown dictatorship – they very thing they wanted to oppose in the first place.

In a lot of ways, I enjoyed Liberator far more than Worldshaker. The action was vivid, but with plenty of breathing time. The romance was bittersweet and tender, the mystery so thick and well, mysterious, it played on my mind with every page turn. Old characters make a reappearance and the rollercoaster of a ride this book puts you through makes it impossible to put down.

This is sure to be a hit with any YA lover, steampunk lover or warfare lover. There is something for everyone in this read that will satisfy all tastes.
