<FONT SIZE="+1">Mind the gap.</FONT> <P> Something odd is going on in the basement of an old house in London. An inexplicable gap has formed, a gap in time that links the present to the past. And twelve-year-old Tom, who discovers the gap while on a visit to his grandmother, is torn between both worlds. <P> Lured by a mysterious voice, Tom leaps into the early eighteenth century, to a time when circus "freaks" like the Bendy Man and the Gorilla Woman appeared at Bartholomew Fair. The voice he hears belongs to Astra, a tiny changeling child, whose limbs are no bigger than a man's thumb. She has called him into the past, because she is convinced that Tom is the only one who can help her and her friends from danger. Doctors are paying a high price for unusual bodies to dissect, and Astra and her friends are prime subjects. <P> But Tom is dealing with difficulties of his own. His mum has cancer and is constantly fighting with his gran. And then he discovers a dark secret in his family's past...a secret that pulls the strands of time together and might just close the gap forever.
