“A challenging read, with finely-drawn characters. The children are set in functional, as opposed to dysfunctional, families—in itself a refreshing change; David’s father is a single parent, but through death rather than divorce. And bereavement—in particular, David’s grieving for his mother—is explored in a sensible and sensitive way. The first of a new series of ‘Contemporary Kelpies,’ this novel is worthy of its famous predecessors.” —Elizabeth Finlayson, School Librarian Journal, spring 2004

“Gill Arbuthnott knows just what a strange and alien place a museum can be and she exploits the other-worldliness to spine-chilling effect. An unusual, enjoyable combination of fantasy thriller and psychological drama with a warmly satisfying ending.” —Kathryn Ross, The Scotsman, December 2003

“A dramatic read, well crafted, well sustained and imaginative. Kate and David’s friendship is based on that between Gill Arbuthnott’s daughter and her friend, and its feeling of unforced authenticity is one of the strengths of the story. The relationships within the two families are also utterly convincing, written without affectation of self-consciousness. Aimed at 8- to 12-year-olds.”—Di Hope, Times Education Supplement Scotland, 14 November 2003

“A most engaging fantasy novel. What might have been a straightforward tussle is enriched and complicated by the personal circumstances of the children, particularly David for whom the temptation to return to a time when his mother is still alive proves desperately appealing. Edinburgh, and particularly the city’s Museum of Scotland, provides the atmospheric setting and props for this tightly plotted novel. Dynamic and satisfying. For readers aged nine to 12.” —Lindsey Fraser, Sunday Herald, October 2003

“What do you mean, we are the keys?” Kate asked incredulously.
“From time to time, certain people are born whose fate it is to aid or thwart the attempts of Chaos to destroy time. You and David are two such people. Look!”
As he spoke, the room turned misty around them.
