Journey from Peppermint Street

In his whole life, Siebren had never been farther than the neighboring village. He could hardly believe it when his mother said he could go on a trip with his grandfather. The night walk with Grandfather from the seacoast to the lonely marsh where Aunt Hinka lived was filled with danger and excitement. And Siebren's visit, climaxed by a tornado and an important discovery, turned out to be an adventure he would never forget. Siebren learns about fear and love and he returns to Peppermint Street to find an unexpected surprise waiting for him.

I can't say much about this because I'm sure I'm missing so much.  It's an adventure, about a very imaginative child and his grandfather, in the Netherlands of a century ago.  It's got scary bits, funny bits, and thought-provoking bits.  I should maybe go to GR and see if some talented reviewer has said anything about it....
