The Lucy Wilson Mysteries: Avatars of the Intelligence by Sue Hampton
Lucy Wilson doesn't want to move from London to sleepy South Wales. But when she arrives at her new seaside home, it doesn't appear to be as boring as she expected.
Ogmore-by-Sea seems to be under the control of a mysterious and powerful force. But why is Lucy its target? And why, when students at her new school start to disappear, does no one seem to care?
With the help of her new friend Hobo, Lucy Wilson must assume the mantle of her grandfather, the legendary Brigadier Lethbridge-Stewart, and defeat an invisible enemy before it's too late.
The Lucy Wilson Mysteries is a Lethbridge-Stewart spin-off adventure and featured licensed characters created for Doctor Who by Mervyn Haisman and Henry Lincoln.
