In this wordless picture book by father/daughter duo Marije and Ronald Tolman, a polar bear and a brown bear float across the sea and come across a beautiful tree, with a perfect tree house built into the branches.  The two bears make their home in the tree, the seasons pass, and other animal friends come and go.  With what looks like crayon, colored pencil, ink, and watercolor, the artists have created a true work of art on each and every page of this book.  The gently changing the colors of the pages and careful detailing of each animal character create a serene mood of harmony and peace, and the complete lack of words invites the reader to create his or her own story to accompany the exquisite artwork.   Highly recommended for all school and public library collections.
