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? Classic storytelling from a brilliant writer and beautifully illustrated throughout by Rachael Dean, with covers by Isabelle Follath. One of these books is never enough!
