Diggers. the second book of the nomes

And Grimma said, We have two choices. We can run, or we hide. And they said, Which shall we do?
nShe said, We shall Fight.
n
nA Bright New Dawn is just around the corner for thousands of tiny nomes when they move into the ruined buildings of an abandoned quarry. Or is it?
n
nSoon strange things begin to happen. Like the tops of puddles growing hard and cold, and the water coming down from the sky in frozen bits. Then humans appear and they really mess everything up. The quarry is to be re-opened, and the nomes must fight to defend their new home. But how long will they be able to keep the humans at bay – even with the help of the monster Jekub?
