So I finished Thunder of Time today and I must have read the previous novel as I distinctly recall a passage referenced in this one, about a woman in an apartment building feeding an iguanodon and treating it like a pet. But that was decades ago and I don't recall much about it other than that - and I don't own the book, so I must have read it as a library book. Oh well. In any case, this one was okay but I greatly preferred the dinosaur bits, not so much when it started playing around with other bits of patchwork history.
In any case, next up on my library book sale purchase stack is Frederik Pohl's All The Lives He Led, apparently about terrorists, Pompeii, refugee camps after a volcano erupted in Yellowstone in 2062, a murder, and a massive disaster that can wipe out all life on Earth. Sounds like fun!
