I guess I'm spoiled to want all the books I read to be amazing, but... it would be nice. :)
Though I wasn't totally sold on this book, my two teenage sons loved it. They loved the first, "Variant", as well. SO, I guess the good news for Robison is that his target audience is enjoying the books he wrote for them.
I do look forward to seeing what else Robison comes up with in the future- he is a decent writer, and often the first few books by an author are their weakest, so there is definitely hope for improvement. I sincerely wish him luck with that.
To sum up: I liked, but didn't love these books. I would recommend these books for teens-- they would probably like them better than I did. Adults who normally only read YA will probably like them, too.
