The first book in this series is really great and well captures the wonder, potential, and thrill of technology. Unfortunately, I don't think that sense of awe is well-maintained beyond the first book. This was OK. Good for the beach, I guess, but not on my list faves.
One minor quibble: I listened to this on audiobook and the narrator uses a TON of highly irregular pronunciations throughout.
I thoroughly enjoyed this book.
Yes, it's very obviously Sanderson's first book, though. Parts of it are trite and pat. He signals a few things too frequently and others too lightly, which makes some of the pacing feel a little jerky.
But overall, it's so youthful, fun, and bright. I love the way he conceives of his worlds and this book is no exception.
