The book tries to intimidate readers regarding customs and superstitions but things are far more relaxed than the book made out to be.
As of my two Ukraine visits in 2011 and 2012, this book is outdated. The book says that clearing customs is very difficult and the customs agents are stone cold stern and foreigner-hating. This isn't true, customs was a snap, agents very nice and my bags were never even inspected either time on arrival to Kiev from U.S. and certainly not when flying within Ukraine. Traditions/superstitions info was also outdated - e.g. it is NOT required to keep up with the host's alcoholism/toasting; anyone, not just the toastmaster, can toast; the young people I spent time with rolled their eyes and laughed out loud at the book's advice on flower giving (number and colors), not opening windows in a train because of "drafts", and many other superstitions: the urban 20-somethings don't believe in this stuff anymore. Contrary to what the book said, money-changing in the cities is a snap, there's a place to do it on almost every block and they don't try to rip you off. I followed the book's advice on gentlemanly manners, holding doors open, standing when a lady stands etc - and it was over the top, the well-bred ladies I was with were noticeably embarrassed by such treatment; none of them were used to it. (Can't say it hurt anything though.) Contrary again to what the book says, nobody batted an eye when I went hatless in winter.
The above info might be useful in small western towns and around old folks, but useless in cities.
The rest of the book is adequate, but you don't need this book to learn it; any guidebook will do, e.g lonely planet beats it hands down re: useful info: where to stay, eat, what to see.
