This book was just as good as its predecessor, if not better.
It's hard to say much that won't spoil Angelfall, so if you haven't read that, you probably shouldn't continue reading this review :)
So this book starts right where Angelfall left off - a seemingly dead girl in her crazy mother's arms with her stitched up sister standing guard. I don't know what else to say about the plot that won't give anything away! I will tell you that Penryn's world is explored even more in this book and no gruesome details are withheld. You really get a feel for the situation that the humans are in after this devastating attack on Earth.
I loved how, like in Angelfall, Penryn never loses sight of what her goal is. She does everything for her cause. I also loved how she explains why she does everything and makes it all seem so logical (which it generally is). Penryn is just such a strong character and though at times she can be cold, she is definitely a favourite of mine.
Like Angelfall, there are many surprises in this book - terrible surprises.
And that's about all I can say without giving anything away! Check out the Goodreads page here!
