Hell Divers 7: Warriors - it is time to win or die

What made this series unique at the start was the concept of trying to survive an apocalypse by living in the sky aboard airships. Once the focus moved down to the planet for the last two books there were times when the series felt like it had gone on a bit too long. The same storm related issues continue to arise over and over and the fights with the sirens have gotten old, but each time the story starts to drag a bit it is the characters that save the day. After a slow start to this one I was once again heavily invested in the outcome before it was over due to the characters and my desire to see them succeed. King Xavier has more enemies to fight than ever before, and that is saying something, and that means that humanity's future is as bleak as it has ever been. Certain Cazadores still resist his rule and cause internal strife while even larger external threats are organizing to come and take the Vanguard Islands for themselves. Once more we get a chance to find out if X, aka The Immortal, can live up to his nickname, or if time has finally run out for the dream of living on the surface.
