I enjoyed listening to this book however it seemed very repetitive.

********SPOILERS BELOW********




Every single time Lucy finds people they just die. It could have been so much better. She could have kept people instead of having every single person die. Thankfully the last chapter of the book she gets two people that don't die. So there is that.

I will be listening to the third book now.

Part 2 is even more action packed and gripping than part 1. Its gritty and full of surprise plot twists that just kept me absolutely hooked the whole way through. I also love Lucy and the fact that we get to experience this apocalypse through someone so ordinary and relatable. It makes the series so much more tangible. I cannot wait for part 3!

An exciting story charting the descent into a post-apocalyptic world. The novel gains in strength and suspension as it continues and has an interesting, strong female protagonist. I'm looking forward to the conclusion.

Action a plenty

Non stop suspense and action; character development in hero plus pulse pounding attacks by monsters; plausible as the world today. Exciting
