Tycho is the second book of the series, but its the first I read.
Do not let the "Book 2" sub-title
run you off. This book works fine as a stand-alone novel. This is a
great science fiction story told from the POV of a teenager who also
happens to be a genius when it comes to things like DNA and such. Sure,
happening to know people who have access to a spaceship might seem
implausible but it makes sense in the circles he was in.
surprised how much I enjoyed this story, except for the hundred times a
sentence ended with "You know". Those were annoying. It also makes it
sound like the story is being told verbally, not written down. I don't
know if the author intended that or not. Overall this story is
well-done, you know...
