Bailey's Window

Just when summer vacation looks perfect, ten-year-old Anna and her twelve-year-old brother Carl hear the news: Cousin Bailey Bond is arriving. He has a nasty reputation and the children soon find out why. Bailey feels put out as well. So, one day he painted a window scene of winter on the blank wall by his bed. He then threw a leg over the window frame and jumped into the picture. So begins a series of astounding adventures for all. (from the cover)
