Having enjoyed both the previous books in this series, I'm sorry to say that this one disappointed me a little. But the positive things first:
I though the basis for the story was amazing, as just when I thought I couldn't dislike the CRU anymore, Kate's writing succeeded in making me seeth with anger at them all over again.
Also, while Alexis annoyed me to begin with, I thought she turned out to be a really cool character; and I loved the little side romance she had with Agent T (who I though was another great character in this story).
Finally, I really enjoyed Frankie's interactions with Joel, Palean and Chrysoar in LA as I thought the humour in those moments lightened the serious feel of the rest of the plot.
However, now for the parts which I felt weren't as great: Emily, and Destroying the World.
In the previous two novels, I thought Emily had been a really awesome character, both as she took care of Pegasus, made friends with Joel and selflessly sacrificed herself for Olympus in the first novel; and as she worked to control her powers and emotions in the second. However, Emily really irritated me in this book, mainly because she seemed to be so angry most of the time, which resulted in her constantly rebelling against listening to everyone else (especially Alexis). Also, she didn't seem to have the same qualms about using her powers against the CRU in the helicopters and planes that she set fire to, or even from using them against Jupiter himself, which had been so strongly emphasised in the second book.
Secondly, I thought that the ending didn't come close to the tension or emotion that Kate created in the previous stories. I was in tears at the end of both, where as this one only caused me to shake my head in disbelief. For Jupiter to be so determined to destroy earth (which although to begin with I thought was a very extreme response, I did think it made more sense further on in the story) but to then to change his mind the instant Pegasus comes back, seemed just too unbelievable. In addition, the fact that Diana was happy to mingle with her clones at the end, in comparison to how furious both Pegasus and Palean became when they encountered their clones; as well as the clones being taken to Olympus, when Jupiter had been so against their creation, also felt quite far fetched.
Thanks for reading this far, and apologies for how long this review has become and that I seem to have done a lot more complaining than praising, but it was just that for me, these two areas seemed to slightly let down what was otherwise another good novel in the Pegasus series.
