Liz has moved house. It seems she's found a suburban utopia - until River Song arrives. There is more to Fetter Bailey than manicured lawns and endless soirees. Dangerous creatures prowl the hedgerows, and something lurks in the freezers.
When a dead man is found with alien technology implants, UNIT investigates. Liz and River are about to discover that those connected to the network are never alone.
In a Yorkshire mining town, strange temporal distortions and rivers of light crossing forests are enough to get the Brigadier's attention, and UNIT is mobilized.
