Wetworld By Mark Michalowski

Why do so many Authors have weird names. In this book the Doctor and Martha are going to a posh cafe but the Doctor takes them to the wrong place.The TARDIS then sinks into a swamp and Martha gets sucked up by a swamp monster. Whilst the Doctor goes off for help. Can the human pioneers help. And why are the natives acting so strange. Looks as if instead of breakfast the Doctor gets a monster instead. Always seems to happen doesn't it.
