It has been thirty years or more since I read ST and it just really hasn't held up. Its not as terrible as AYTGIMM, but it is pretty bad.
Snow Treasure is loosely based on true events during WW2 when Norway removed its gold from the country so that it would not fall into the hands of the Nazis.
Children rode their sleds down to the beach with hidden gold bricks where a ship took the gold to the US.
The things that make this book unappealing are things that I missed when I was a kid. Before the Nazis invaded Norway, the folks in the book say things like, "We've no quarrel with anyone and no one has a quarrel with us." page 17. I don't know...it just kinda reminds me of First They Came. Also this dude named Per Gerson, he's just a jerk.
Basically it's just that the book is very dated. It took a long time to finish this one. I'm interested to know what kids think of this book today.
