Contemporary, Teen & Young Adult 

A boy called Joachim acquires a strange old Advent calender - and uncovers from it the story of a girl called Elisabet, who disappeared from her home fifty years earlier. Elisabet has been taken back through time and right across Europe to Palestine, to see the Holy Family in Bethlehem. Two thousand years of history flash by, and angels, shepherds and wise men join her on her joyful pilgrimage. It is Joachim who, through the Advent calendar, makes it possible for her to come home. THE CHRISTMAS MYSTERY transcends all barriers. It has already proved a great success with colour decorations for children, and as a paperback for adults. It has now been abridged for younger readers and freshly illustrated by a talented new young artist. The qualities of wonder and enquiry that readers loved in SOPHIE'S WORLD are as strong as ever in this beautiful and mysterious story which appeals to believers and non-believers alike. - from Amzon
