Works as a set of brief fascinating travel memoirs. Also works to introduce readers to excellent new authors. Also inspirational - up until the last story, world travel was something that happened to the authors, mostly when they were young... but in the last one, we meet two people who had to work against obstacles to have the horizon-expanding adventures. I thoroughly enjoyed it, and highly recommend it. And, yes, it is definitely a good idea for young people to get a passport and go exploring, or at least to take part in a semester abroad.
Unfortunately the book cover gave me an incorrect idea what it was about. When I first picked it up I thought it was SF, or at least "alternative auto-biography" (wouldn't that be a cool book?). Then I thought, well, at least it might have some graphic novel kinds of illustrations (which it didn't, but at least it did have some pix of the authors' youth). But no, I guess it's meant to be merely universal, given that the memoir essays cover so much of the globe and so many eras, and so a more earthbound illustration would have had to choose what part of earth to cover.
Anyway, I repeat, very enjoyable. Maybe not all that important to folks other than the target audience, but well worth the time to read.
