Father Thames

Serial rule breaker Jemima Mallard has done the unthinkable – she’s joined the Youth Police Department (YPD). Is she serious, or is she just trying to track down her mother? Fellow YPD officer Nick Mallard isn’t sure. Before he can test her loyalty, they come under attack. From the Thames Barrier Reef to Trafalgar Swamp, strange ships have breached London’s defences. The city hasn’t seen anything like these masked raiders before – adults and kids who work together. But orders are orders, Jem must find a way to stop them.
