Newbery, Caldecott winners announced

Jack Gantos' "Dead End in Norvelt" has won the John Newbery Medal for the best children's book of 2011. Chris Rashka's "A Ball for Daisy" won the Randolph Caldecott award for best illustrated story.

The Newbery and Caldecott prizes, the most prestigious in children's literature, were announced Monday by the American Library Association. Gantos' novel follows the improbable adventures of a boy named "Jack Gantos," while Rashka's picture book recounts the saga of a dog whose favorite toy is destroyed.

Both winners are well established in children's publishing. Gantos has been a finalist for the Newbery and National Book Award. Rashka won the Caldecott in 2006 for "The Hello, Goodbye Window."
