I liked this book, but I am a little disappointed about the total absence of an evolution after the first novel. Leviathan Wakes was a very entertaining and promising novel, but despite that fact that Caliban's War remains a very entertaining book, it doesn't fulfill any of the promises from the first novel. And after reading about 3 very interesting Solar Systems in McAuley, Reynolds and Robinson's novels, Corey's universe feels bleak and common. But I will wait to read the third volume for a more definitive opinion.
