Abby and Riya are:

Best Friends

Complete opposites

Living on different continents

Currently mad at each other

About to travel around Europe

Since Riya moved away with her family to Berlin, she and Abby have struggled to be there for one another, and they haven't spoken in weeks. But Riya is pretty sure she knows the perfect way to make things better - a grand tour of European cities. Two weeks, six countries, unimaginable fun.

Can the lush countryside and dazzling cities of Europe fix their friendship, or does growing up mean growing apart?
