Her first book, The Ugly Vegetables, was published in 1999. She has subsequently written and illustrated numerous children's books and novels, including the Pacy series and Where the Mountain Meets the Moon which was a recipient of a 2010 Newberry Honor book mention. Her most recent novel is Starry River of the Sky. I have not yet read Starry River of the Sky, but I read and loved the Pacy series, especially Dumpling Days and I particularly enjoyed Where the Mountain Meets the Moon.
In addition to these books she has written two early readers, Ting and Ling Not Exactly the Same and Ting and Ling Share a Birthday. Rose and Roni love both of these books. They are about twins and are comprised of six short chapters per book. The illustrations are adorable and the stories are cute and for the mom of twins oh so spot on.
