Have you ever dreamt of travelling through time? Andy and Hayden Abercrombie hadn't, but it happened to them anyway. From racing in a chariot to being chased by a T-Rex, from singing with mediaeval knights to fighting hungry snake dragons, the brothers squabble their way through one extraordinary adventure after another. If the brothers can stop fighting each other they may be able to find, damsel in distress, Blythe Fairweather's missing brother and work out a way for them all to get home. Written with readers aged 9 to 12 in mind, The Incredible Time Travelling Marble Contraption is a hilarious dash through history for both boys and girls to enjoy.
