Somewhere between 3 and 4 really. I like the vicarious travel around Russia, and the in the moment-ness of the stories, but the writers weren't so great at bringing the characters around them to life as well as I'd like, since they seemed like potentially interesting people. Probably just due to inexperience ??
Maybe the subject, hitchhiking, forced too much "in-the-moment". Still, glad I read it--the last writer was perhaps the bravest and most interesting. Imagine, a young girl putting herself on the road, all alone, in Arabic countries-not knowing the language, and winning everyone over--no trouble, or so she says.
Anyway, a quick, light read.
