Synopsis of The Chaos Clock

Kate and David are eleven-years-old and best of friends, playing football and doing their museum project together. But in Edinburgh, where they live, time is coming unstuck and the past is breaking loose. Old Mr Flowerdew needs their help in the war between the Lords of Chaos and the Guardians of Time, centred around the mysterious Millennium Clock at the Royal Museum. Can Kate use her grandmother's golden necklace to restrain the power of Chaos, and will David be able to help the Guardians, even if it means losing his mother all over again? This is a thrilling read which uses real, recognisable locations in and around Edinburgh for the main action.

Synopsis of The Chaos Quest

It is eighteen months after the events of The Chaos Clock, and Kate and David are now at secondary school in Edinburgh. David is struggling to come to terms with his new stepmother, and Kate is being expected to take more responsibility for her younger brother. But time never stands still for long. They soon become involved in a race to prevent the Lords of Chaos from tricking Erda, the Stardreamer, into losing her power. Even with help from Morgan the Hunter, can they prevent the barriers between times being blown away forever?
