A favorite children’s book – “Trouble for Trumpets” by Peter Dallas-Smith.

This may be a favorite largely due to the captivating illustrations, by artist Peter Cross.

The book imaginatively tells the story of the change of seasons and the passage of time, flowing like a river through the seasons of the year. It is richly illustrated with beautifully detailed, colorful drawings combining nature and cutaway views offering a glimpse into a visionary, gadgety, original world, existing partly underground.

I especially like this customer review:
