What did you think of the story structure? It was excellent, with the different planets and characters, the reader isn't distracted from the main plot.
What do you think will be your lasting impression of this book? The amount of work the author has spent creating this book. Each sketch fits the chapter it introduces and each poem at the beginning of the chapters appears to offer a summary of what is to come.
Was the time period important to the story? Not really, it could happen 10 years from now or 100 years from now, the time period was purely fictional.
Disclosure: I received a review copy of this book from the author.
