Doctor Who and the Power of Kroll
The enormous, octopus-like Kroll resided deep within the planet's swamps of steam and humidity. Kroll was viewed by the local swamp warriors as a vengeful mythological being. Kroll represented a danger to the avaricious extraterrestrial technicians' money-making strategy. The Fourth Doctor and Romana must contend with the technicians' incompetence, the Lagoon residents' distrust, and finally Kroll's might as they look for another piece of the Key of Time. The Key to Time Sequence includes the book THE POWER OF KROLL. The RIBOS Operation, The Stones of Blood, and The Androids of Tara are also available.
