When I was young, my mother was very disturbed that in second grade, I was still reading picture books rather than chapter books. My father read my brother and I part of a chapter book every night, and I liked pictures. I was pressured away from picture books, only to become an art history(and math) major in college. Sometimes, kids do know what is best for them.
I do, however, now LOVE chapter books. Reading is one of my great joys in life, especially reading Terry Pratchett books. So imagine my delight at a Terry Pratchett picture book, illustrated by the incredible Paul Kidby! While his visions of Terry's characters don't always match mine(the Sam Vimes in "Where's my cow?" is closer to my mental image), he is an excellent artist. Sometimes, he paints a person or place and I just go "wow"! The Librarian, Vetinari, Death, Granny Weatherwax, Mr. Wuffles, Detritus, Rincewind, Mustrum Ridcully, Carrot, Nobby Nobbs--all rendered perfectly alive. I wish there had been more pictures of Lady Sybil and Agnes Nitt.
To make it even better, Terry gives his commentary on each picture, including how he thinks the characters should look.
