My Grandmother's Clock by Geraldine McCaughrean
In grandmother's house there is a grandfather clock, but it does not go. The hands on its big face never move! But grandmother doesn't need the clock to show the time, she says that there are so many other clocks telling her the time. She can count the seconds by the beating of her heart, an hour in the time it takes for the bath water to get cold, a week by the dust that settles on the grandfather clock and a lifetime in birthdays, friends and in what you can remember. Lyrical, moving and beautifully illustrated, this is a book to be treasured.
