The Children's Hour is a science fiction novel by Jerry Pournelle and S.M. Stirling. The stories Children's Hour and Asteroid Queen were first published in Man-Kzin Wars II and Man-Kzin Wars III, respectively.
In the Children's Hour, Chutt-Ritt, the new Kzin governor of Wunderland in the aftermath of the fourth attempt to invade Sol, proves to be such a cunning and dangerous enemy that Earth-based UN Forces send a small party to assassinate him. Using an unorthodox entry into the Alpha Centauri star-system (the Kzin don't know quite literally what hit them), the small band of humans find themselves hiding in plain sight on a world under the thumb of Kzin occupation. With its shifting alliances and rekindled romances, this story is a loving tribute to the classic "Casablanca."
In the second story, Asteroid Queen, Hari and Ingrid are still on Wunderland, active in the resistance. Meanwhile, an asteriod miner finds a very unusual rock and unwittingly awakens a deadly Slaver from his 1.5-billion-year slumber in stasis.
