Daleks - Invasion Earth

 was a book written by Christian Peterson, considered the definitive account of Dalek attacks on Earth in the 21st century.

At least in part, it focused on both the Battle of Canary Wharf and the 21st century Dalek invasion, sourcing information from survivor testimonies. (PROSE: The Secret Lives of Monsters)

"Some survivors were also able to provide information about the Daleks themselves. It seems there were four of them in all - led by a Dalek with a black casing, as opposed to the more usual bronze armour. These Daleks formed the Cult of Skaro, a group established by the Dalek Emperor to dare to imagine. They tried to think like their enemies, to understand their thought processes and determine their strategies. To this end, these Daleks even took names. Led by Dalek Sec, the other Daleks were Thay, Caan and Jast (some reports mention a Dalek Rabe, but this seems to be an error."
