Christmas miracle

All the events described in this
book begin just a couple of weeks before Christmas and take place in the city
of Zurich. All members of the Rosenberg family live a calm, slow-paced life.
The head of the family, Martha Rosenberg has a job she likes a lot in a large
Swiss bank. Her children, Mark and Greta, live the lives of ordinary teenagers
with school on weekdays and various exhibitions and museums on weekends. And nothing meant trouble it seemed.
No one thought about it anyway.
