this is another grab bag book...if you want to see the rest just search 'grab bag' in the navigation bar at the top of the page.
i'm a scandophile...and i was given a lovely trip to copenhagen for my college graduation by my mother. the day we visited the little mermaid it was christmas and about 0 degrees. the wind coming off of the oeresund strait was even more frigid. but it was worth it, she really is as lovely as everyone says.
i've never read any of "the happy hollister" books, but i'm glad to have this one to start with.
