I liked the beginning of this and felt the characters were well drawn. Most of the above comments mirror my own. I dooubt I have much to add but the travel scene did make me lose interest. In one of my own novels, I lost an agent over the same 'getting to one place from another' situation. I have now cut it out almost in its entirety. I think as we are writing sometimes, that we feel the need to take the reader on our character's journey, forgetting that a lot of people hate car trips.
Great potential here, though. Good luck with the agenting thing!
