Wow, that's quite a collection there!
And that's only page 1!
First mistake is 6 words in... That has to be a record!
Corrections as far as I can see...
beautiful, (no capital, needs comma)
Daytona Beach, Florida (needs comma)
grammatical break down here... There's a compound mistake that I can't really count properly.
Anyway, the sentence should be thus...
This story begins on a beautiful, sunny day in Daytona Beach, Florida with David Braymer, a 45-year-old, single man who works as a 12th grade science and astronomy (I'm guessing they got the wrong word) teacher at the local high school.
WTF do they keep using "Now" for?!
Cheral's place is how close to the cape? Oh, real close.

What book is this?!?!
I might have to buy it and correct it before sending it back to the publisher.
