A bit wordy and overly technical at times, but overall very informative.

At first I gave this book a 5 and then a 4 but if I am being honest it is a 2. I felt bad and weird about not liking this book because it's about dying kids and everyone seems to cry enough to fill an ocean when reading it. The main characters are pretentious know it all brats most of the time. They are unrealistic and boring.
