Constructive Criticism Please...?

LOL it's actually pretty good & SUPER sweet. You have talent! My only suggestion would be to edit it for grammar and such, because spell check won't get everything for you. And, also, since this is the beginning, you should play around. Maybe write the Jake-Lindsay conversation and head in a new direction. What if they teased each other a lot? What if they were a bit awkward? Or maybe change the way you write, or change the first paragraph of the story. A famous author once said that the first 100-1000 words you write are the worst. My suggestion is that you get through those words as fast as possible and keep trucking. Remember, this is YOUR novel. Anything can happen. Jake could be the one that pushed Maria in front of the truck. Hell, Jake could be a ZOMBIE! As long as you have the WHY behind the actions, it's all cool.
