The barren, beautiful Cumbrian fells provide the bewitching setting for the adventures of Bill and Harry, two children who find wonder at every turn as they experience the Hollow Land. Everyday challenges give a daring edge to this rural work and play. There are mysteries to explore and uncover, like the case of the Egg Witch, and everyone is curious about the Household Name, a visitor from London, moving into the jewel of the territory, Light Farm.

Kate Tranter is fatherless - or is she? The evidence of the tombstone she finds in the churchyard seems conclusive. And yet... The tombstone disappears and Kate is left with a mystery about which her family either knows nothing or will tell nothing. Her search for the truth leads her to Sattin Shore: and the way to Sattin Shore turns out to be a way into the past. Her two elder brothers, her grandmother, her new friend Anna and her missing father all have a part to play in Kate’s search to fit the jigsaw pieces of past and present to find a new picture for the future.

After being horribly mistreated at a government animal-research facility, Snitter and Rowf escape into the isolation - and terror - of the wilderness. Aided only by a fox they call "the tod", the two dogs must struggle to survive in their new environment. When the starving dogs attack some sheep, they are labeled ferocious, man-eating monsters, setting off a great dog hunt that is later intensified by the fear that the dogs could be carriers of the bubonic plague.

Kitty’s not known for sensitivity or tact but she’s been through it all herself - her mother married the silver-haired, chocolate-bearing, goggle-eyed Gerald.
