Amy and Roger's Epic Detour by Morgan Matson

It wouldn't be a road trip without some detours...

Amy Curry is not looking forward to the summer.  Her mother decided to move across the country and now it's Amy's responsibility to get their car from California to Connecticut.  The only problem is, since her father died in a car accident, she isn't ready to get behind the wheel.  Enter Roger.  An old family friend, he also has to make the cross-country trip -- and has plenty of baggage of his own.  The road home may be unfamiliar -- especially with their friendship venturing into uncharted territory -- but together, Amy and Roger will figure out how to map their way.
