Taking a multi-media approach, Scholastic Inc bring us Spirit Animals — a series of fantasy novels for young readers that tie into an on-line interactive game. “In the world of Erdas, every child who comes of age must discover if they have a spirit animal. This rare bond can unlock incredible power. A dark force has risen from the past, and now the fate of Erdas depends on four brave kids . . . and on you.” So far they have released four books in the series (by a variety of authors), with another one coming later this year and two more slated for early in 2015. The Spirit Animals web site has more details of course. “Read the books, then join the adventure!”
