Liz at A Chair, A Fireplace, And A Tea Cozy reports that the Children's Literature Association gives an award to books of "high literary merit." Called The Phoenix Award, it is given to older books. Right up my alley.
This year's winner is Howl's Moving Castle by Diana Wynne Jones, originally published in 1986.
As luck would have it, I'm reading Wynne Jones' 2006 book The Pinhoe Egg.
