The Correct Reading Order?
"The Children's Hour"
"The Asteroid Queen" (FTL introduced)
"In The Hall Of The Mountain King" (Tyra's father referenced)
"Inconstant Star" (Tyra's father rescued)
My only uncertainty is whether "Iron" belongs before or after "In The Hall..." If the latter, then the reading order can be summarized as:
the Pournelle-Stirling trilogy
the Anderson trilogy
Further rereading and other readers' comments should clarify this point.
Man-Kzin Wars X: The Wunder War, a tetralogy by Hal Colebatch, is also relevant. These ten works could be re-presented in three volumes. But there are many more Man-Kzin Wars installments. Meanwhile, Ringworld has become a tetralogy and the Fleet of Worlds has become a trilogy. Known Space is vast indeed.
