I’m always up for a good time travel book and I enoyed this one. It was nominated for a Hugo in 1973. It lost to Isaac Asimov’s “The Gods Themselves.”
Written as if Dr. Robert Anderson, a distant relative of Poul’s father left behind this account as part of his memoirs. It’s about Jack Havig. Even as an infant he’s been able to time travel.
Havig finally gets comfortable with Dr. Anderson to tell him all about the events in his life. No time machine necessary. Havig wills himself to travel. The turning point is near the crucifixion of Jesus. He meets other time travelers and travels into the future to the Eyrie. It’s ruled by Caleb Wallis, a bigoted ego maniac who is from 19th century America.
Wallis wants to go farther into the future where New Zealand’s Maurai dominate the world following a nuclear holocaust. He wants to bring them down and once again bring about an industrialized society. At first Havig joins him but eventually rebels.
Havig’s adventures in the early 13th century Byzantine Empire and Constantinople are a grisly representation of the time as the Crusaders ransack that part of the world. Wallis’ men destroy the family Havig became a part of and he’s out for revenge.
With the help of Leonce, a woman from a Glacier era of the future, Havig attempts to destroy the Eyrie. It means a lot of back and forth travel in time to get recruits.
Anderson and time travel go hand in hand and this is one of his best. It’s not part of the Time Patrol series.
