Topher's cat, Ka, is not always who she seems to be.

Sometimes she disappears for days and all that Ka has left by his bedside is a little stone carving of a cat.

One days Ka leaves a clue on Topher's computer. She types Bubastis and soon Topher finds himself time-travelling to Ancient Egypt where Ka is in terrible danger.

Julia Jarman's characters are acutely observed from real life -- she manages to introduce contemporary issues such as single-parent families and disability and blends them with historical fact and fantasy in this fast-paced novel.

With Ancient Egypt high on the agenda in National Curriculum History, this book is already much in demand with children, teachers and librarians.
