This book is so much fun. I mean, I knew I would like it based on the fact "epic" is in the title (don't judge me), but I hadn't expected to like it this much. 
 Amy's going through a rough time. Her father died in a car accident--which she feels responsible for--and her mother moved across the country to get a head-start on what will ultimately be their new lives. Amy hasn't driven a car since the accident, so she's surprised/annoyed when her mother says she has to bring the car over to Connecticut from California--with a "friend of the family," Roger, (who Amy hardly even knows) to drive. 
 Amy's mom planned out their entire trip, making hotel reservations at key stops, but something makes them ignore it. They don't want to follow the route. And even though they barely know each other, they throw out the itinerary and start planning their own trip across the country. 
 The entire thing felt so real to me. Amy & Roger are both fantastic characters. We're learning who they are at the same time they're learning about each other. Needless to say, they form a connection. At some point, they become friends. And they both have issues to work through, figuring out who they are and where they're meant to be. 
 And there are little things thrown in there that add to the road trip fun. Receipts from various diners and burger joints. Roger's playlists (he has excellent taste in music). And doodles and postcards and everything you expect from living out of a car for a week. It's like your own personal scrapbook. 
 It all felt so genuine, and it brought back that old urge to drive cross-country myself. I just need to find myself a Roger.
