Description :- 

The Year of Living Danishly:

When she was suddenly given the opportunity of a new life in rural Jutland, journalist and archetypal Londoner Helen Russell discovered a startling statistic: the happiest place on earth isn’t Disneyland, but Denmark, a land often thought of by foreigners as consisting entirely of long dark winters, cured herring, Lego and pastries.

The Atlas of Happiness [Hardcover]:

- Feeling terrified of that upcoming job interview? Take inspiration from the Icelanders and get some Þetta reddast, the unwavering belief that everything will work out in the end.- Lost your way in life? Make like the Chinese and find your xingfu, or the thing that gives you real purpose.- Too much on your plate? The Italians can help you learn the fine art of dolce far niente, aka the sweetness of doing nothing at all.

Gone Viking:

Frazzled mum Alice Ray likes to think she’s on top everything – she has FOUR bags-for-life in the boot of her car for heaven's sake. But after spectacularly embarrassing herself at work, she finally gives in to her sister’s pleas to take a much needed break.But this is not the luxury spa holiday Alice hoped for – instead, she finds herself in Denmark, in the middle of nowhere, on a ‘How to be a Viking’ getaway.
