"The Happiest Book" by Alex Ostrowski.
"In one way or another we are all looking for happiness. Some people even say that man's sole purpose for existence is to hunt down and capture this intangible and elusive treasure. In 2006 researchers at The University of Leicester concluded that Denmark is the happiest country in the world - this was good enough for me. In March 2008 I made the decision to visit happiness, and embarked upon a pilgrimage to find it. My experiences are presented in this book.
Only one copy exists. "
