Bright Before Sunrise, by Tiffany Schmidt

Jonah can't stand living amidst the snobby kids in Cross Pointe.  He's give anything to be back in Hamilton with his friends and his girl Carly.  And of all the people in Cross Pointe, the most annoying of all has to be Brighton -- the ever-chipper do-gooder who keeps nagging him to join in one of her volunteer projects.  Why can't she leave him alone?  For Brighton though, Jonah is a big mystery -- why is he so rude and mean to everyone, even when she is being so nice to him?

And then one night, fate brings them together on an adventure where the angry young man and the self-centered young woman will discover there's a lot more beneath the surface.  And they will discover that they are simply perfect for each other.

It's a classic no-surprises romance, but I like those and (assuming you like a fun romantic book) you will too.  The set-up is a bit too obvious and the starting points are a bit too convenient, but there's the growth in the relationship felt organic and perfectly natural.  Both Jonah and Brighton are interesting young people and it's easy to see how they could hit it off once we get through the initial  posturing and misunderstandings.  And that's basically what one wants from a romantic story.
