Wild Horizon - The Ghost Herd

They came to Kenya to begin again. Someone was making the wildlife disappear. Fifteen-year-old Tess Mercer never asked to exchange her life in Britain for a wildlife rescue centre in Kenya. Her mother calls it a fresh start. Her adventurous brother Finn thinks it is the greatest thing that has ever happened to them. Ten-year-old Bea is fascinated by the unfamiliar sounds of the wilderness. Tess just wants her old life back. Then, on the family's very first night at Kijani Wildlife Rescue, an injured elephant calf stumbles onto the road carrying a damaged satellite collar. There is just one problem. According to Kijani's tracking system, the elephant wearing that collar is still travelling nearly eighty kilometres away. The following morning, experienced ranger Samuel Oduor is missing. And the mysteries are only beginning. Waterholes mysteriously run dry. Wildlife begins moving towards neighbouring farms. Powerful veterinary medicines disappear. Unmarked vehicles travel through the reserve after dark. Most disturbing of all, Kijani's digital map shows elephants travelling normally across the landscape... but the real herd has vanished. As Tess, Finn and Bea adjust to their extraordinary new home, they join forces with sharp, determined local teenager Amani Kilonzo. Piece by piece, they begin uncovering evidence of something far bigger than a missing elephant. Someone is manipulating Kijani's wildlife tracking system. Someone is stealing its water. And someone intends to turn a conservation emergency into an opportunity worth millions. With the first great storm approaching and an entire elephant herd in danger, the young investigators must decide when to trust their instincts—and when courage means stopping, listening and asking for help. But discovering the truth is only part of the challenge. They still have to prove it.
