When Alex and Ruby fall through the mirror in their aunt's house, they find themselves in a different historical period, each time with a different task to perform before they can return to the present. From Edwardian crime capers to Victorian Christmasses, their time-slip stories are always exciting and beautifully told.

A Victorian Christmas is lovely - all the food and candles and games and singing - unless you're poor, motherless Edith who is condemned to be sent to a cruel boarding school on Boxing Day. Can Alex and Ruby persuade her strict father that home is where the heart is instead?

Full of action and humour and featuring exciting black-and-white illustrations throughout, this is another superb time-slip story which brilliantly brings history to life as part of an adventure.

'A clever vehicle for introducing the differences between then and now in an accessible way, with a fast-paced plot and a lovely spooky ending' - The Times on A Chase in Time
