"Once there was a baby bear who lived at the top of the world..." So begins Sleighbear, a gentle, often humorous Christmas story by award-winning author/illustrator Virginia Wright-Frierson. With a tap of the screen, you can watch her original watercolors come to life! The animations, music, and sound effects let you feel the Christmas magic in a way that no traditional holiday book can bring. Sleighbear is a story of friendship, determination and the joy of Christmas. A polar bear baby sees her reindeer friends flying and wants to help carry Santa's sleigh too! You'll fall in love with the little bear and her owl, fox, and reindeer friends. Play hide and seek, tug of war, and practice flying with the little bear and her friends. Santa and Mrs. Claus come up with a wonderful solution that makes little bear so happy! The text appears on the pages in either English or Spanish, chosen by touching the language button in the main menu hidden at the top of each page. Accompanied by soft music, the story is beautifully read in either language or can be muted so that it can be read to a younger child by an adult or older child. Children can interact with the text by touching a small red mitten on each page to produce sound and action events. Touching the Christmas tree green arrow turns each page. As an author/illustrator, Virginia Wright-Frierson is most noted for her scrapbook series of three nature books, each of which won placement on the John Burroughs List of Nature Books for Young Readers (A Desert Scrapbook, An Island Scrapbook, and a North American Rainforest Scrapbook). Virginia is also a fine artist, most well known for the large, inspiring mural painted on canvas and installed permanently on the ceiling of the Columbine High School in Littleton, Colorado. Her recent exhibitions have included watercolor and oil paintings.
