What if dinosaurs survived and they coexisted with humans on Earth! This was a great premise and a very good series. I really enjoyed the biological creativity, rather than mechanical. ( )

30 años despues no recuerdo si me gusto pero solo porque me acuerdo de la trama, tiene que ser bueno! ( )

Harry Harrison is very good in creating alien worlds, even if it is in the past. The depiction of this reptilian civilisation against primitive hunters is very realistic. ( )

This was a great satisfying read overall. The ONLY quibble I have is the first 100 pages. You are dropped into a reptilian culture immediately with no preparation for the reader. The culture and its language is unknown and you are left to puzzle out what is going on.... it is confusing and if I did not give it 100 pages I might have given up on the book.

Unknown to me at the time was there was a detailed description of this culture at-the-end of the book. I am not the type of reader that looks to the end of the book first. By the time I got there I was familiar with everything and it was superfluous as far as I was concerned. I think that section should have been placed as an introduction...not an epilogue. Then the first 100 pages would have made more sense.

Therefore I strongly recommend That the new reader look at the descriptions of this alternate world, where dinosaurs are not wiped out by a meteor strike, and its cultures before reading the novel

An excellent novel and the first of the series. I shall actively search out the rest of the series as well as look for more books by Harry Harrison. ( )

It'd be one star, if not for the man-dino sex. Other than that, this book might as well have been written by Heinlein. ( )
