It's one thing to be friends with someone, but going on a trip together? Totally different story. A new graphic novel by Jillian Tamaki and Mariko Tamaki captures that dissonance: Roaming follows two friends from high school reuniting on a trip to New York City during college. But there's a new, third pal in the mix – and pretty soon, it's clear the vibes are off. The Tamiko cousins spoke with NPR's Ayesha Rascoe about how the way a person travels reveals a lot about their character, and why that experience was much different in 2009 – the year the book is set – than it is now.
