Many adult authors have more trouble with their first children's books than they expected, but Singer nails it the first time out. She carefully and discreetly lays all the pieces in place for a hugely emotional climax, and weaves just a hint of magic throughout. All the characters -- Robert, his mother, Edith, her husband Ernest, and others -- are fascinating and complex, but none more so than Niker, who is not your average bully.
This sort of lovely, lyrical, deeply moving, vaguely magical character study is becoming quite a specialty of the Brits: David Almond, Tim Bowler, Peter Dickinson, and others have written books with a similar tone. The BBC has even turned this book into a TV series. Though it's certainly not aimed at action-adventure buffs, even some of them will be captivated by the mystery and gentle suspense.
