Sad that Harry's ending?

Not to worry, the next Harry Potter might just be on the horizon already:

Roderick Gordon and Brian Williams were signed by Chicken House publisher Barry Cunningham after he tracked down an early version of their book "Tunnels" that was self-published.

"I knew from page one that Harry Potter was magic. Reading 'Tunnels' gave me the same thrill," said Cunningham, who has also achieved worldwide publishing success with the children's books of German writer Cornelia Funke.

"Tunnels has it all: a boy archaeologist, merciless villains, a lost world and an extraordinary journey to the centre of the earth," Cunningham said after first stirring up interest at the international children's rights fair in Bologna.

Fourteen-year-old Will Burrows lives with his family in London. He has little in common with them except for a passion for digging which he shares with his father. When his father suddenly disappears down an unknown tunnel, Will decides to investigate with his friend Chester. Soon they find themselves deep underground, where they unearth a dark and terrifying secret - a secret which may cost them their lives.
