Nikki Spencer choses "The Ten Best: Children's Audio Books" for the Independent.
Selections include Frank Cottrell Boyce's Millions (read by Stephen Tompkinson), I, Coriander, by Sally Gardner (read by Juliet Stephenson), Diane Wynne Jones' Howl's Moving Castle (read by John Sessions), and The Beasts of Clawstone Castle, by Eva Ibbotson (read by David Tennant).
Audio books can save a long drive and they're great to clean to as well (if one must clean that is...)
