Alright, that was longer then I thought it was going to be. heh.
On the 5th paragraph you start dialogue between Cassie and Alex. I have no problem with what they say, but you need to make new paragraphs each time someone talks. That goes for the rest of it too.
Also in that paragraph, you say "headed back to his house" which I think is supposed to be her.
I also noticed that the 10th and the 12th paragraph ended with some statement, but they both started with God. That seemed to stand out. You may want to change one of them because it doesn't flow well.
When he is on the bus the first time and gets woken up by the driver, there is an odd sentance. "I came to as a man"...it just sounds weird. I think there needs to be a comma or something in there.
I also found the whole Jules thing a bit odd. Just before he meets her, he is in the bookstore and is too shy to talk to the girl. But when he see's a hot girl on the bus he sits right next to her. That just seems to forward for his character. Its important for the plot though, so maybe if the bus was crowded and there were only a handful of empty seats, and that was one of them. Just a thought though.
Thats all I picked up from a beta standpoint.
I really like whats happening. At first I thought that this was a bit like "On the Road" so I thought the reference was really cute. But the more and more I read the more I realized that it reminds me a lot of "The Catcher in the Rye". If you haven't read it, you should.
All in all it's pretty well done. I'm impressed. There are some minor repetative things (like how he drinks a LOT of coffee! ) but nothing that ruins the story.
If you write more of it, I'd like to hear it. I am curious to know where this is going.
