I both loved and hated this book. Under the best of circumstances I have a hard time with books where alternating chapters are told by different people. I have an even harder time when one of those narrators is compelling and one is totally not. This book has half of it written by what is basically a sentient spider race. And while there is a great thought experiment here “How would a community of spiders who achieved sentience go about evolving?” I just did not care about it and wanted to get back to the humans on the giant ark who were having some real problems. So, this is a great book and well-written and all the rest, but I sort of hated half of it and loved half of it. The ending is satisfying and I am pretty sure I will not read the sequel.
