Join actress, math whiz, and bestselling author Danica McKellar for a reading, Q & A, and book signing at Children’s Book World.  In her delightful new picture book in the McKellar Math series, Ten Magic Butterflies, readers will join ten flower friends for a night of excitement that mixes a little math with a lot of magic.
