Robin has just moved to a new town. Everything is gray here: the houses, the cars, and most of the people. It's hard to get used to.

Where have all the colors gone? The girl tries to figure it out, finds allies, and gets on the trail of an incredible mystery. Together with her friends, she decides at all costs to find out what is happening behind the walls of the Gray Factory.

Allegorical and inspiring, a truly detective story about the fight against monotony and the right to be yourself.

Following the worldwide success of the books about the adventures of brave mice, Torben Kuhlmann returns with a new, beautifully illustrated book.
