I love the way McCully brings this inspiring story to life - four boys, in France under Nazi occupation, discovered the incredible Lascaux caves while looking for a lost dog and hunting for a legendary gold stash! Jacques, inspired by his passionate history teacher, recognises the cave paintings immediately for what they are, and knows that they are a treasure worth more than gold - a language spoken across the millennia, alive and perfectly preserved.

McCully's illustrations have something of a 'Famous Five' feel about them, and are wonderfully evocative - and her representation of the cave paintings really inspires wonder in the reader. She has, through the book, managed to make any child reading feel as if they, too, are discovering the cave and its paintings for the first time - quite a feat! I think any child who encounters this book will grasp something of the thrill an archaelogist must feel when they are the one to first see or touch something that has survived hundreds or even thousands of years undiscovered. Highly recommended for use in homeschool or in the classroom - I know it may be hard to find, but it beats so many drier non fiction books out there on a similar theme!
