Pebble People Book Series.
Pebble People are a small group of best friends who are made from stone, but unknowingly to humans they can walk, talk, smell and care for one another. They do not feel pain because they are made from stone, but they still run away from dangers just incase they become damaged. They can breathe under water and often find this a good way to hide from anything dangerous.
Shelly tells her story of her adventures and mishaps with the dinosaurs about 65 million years ago, when the non-bird dinosaurs became extinct.
Seeing the planet on fire after an astroid hit and eventually waking up to an ice age where she first met her future best friend 'Flint', who was being chased by Cavemen.....this ending will lead on to the second book.
