Wandering book

Packing my bag this evening I suddenly find a strange object, a book that isn't mine...

I'm not lost...
I'm a book on a journey,
may I travel with you..?

A sticker on the cover indicates that 'de klokkenluider' from Tomas Ross didn't get in my bag by accident.

This book is on a journey...

According to the instructions in the book, I've just found a wandering book. I can read it, and sent it on its journey again: read and let go!

[ to the anonymous donator: thanks... ]
