In the middle of summer a small town is beset by a blizzard that enshrouds it in a blanket of snow. The cause is unknown and all contact with the town is lost. The player characters are hired to investigate the town and put a stop to the blizzard if at all possible.
(An adventure written in the more rigid and hand holding "old school" style and quality level of original fantasy adventure modules from the early to mid 1980's)

You find a book in the library, then when you start to read it, seems to change from pages of words to pages of images that seem to live and move. If you touch the page after the images appear, you travel into the story and now live in that world.
There is a book on that world, that leads back to this one.
