Jolabokaflod
Icelandic for “Christmas book flood”
“The culture of giving books as presents is very deeply rooted in how families perceive Christmas as a holiday. Normally, we give the presents on the night of the 24th and people spend the night reading.”

I really must visit Iceland next year. It sounds like my kind of place.
