These " Time Scout " books has a very good premise, but after reading 2 out of 4 books, I can't really say I'm impressed, as the story mostly centers around the scouts living on one of the so called Time Terminals, and there is not as much time travelling as you would expect at all. But, since there is only 4 books, I'm kinda dedicated to finish them off, and most of them are around 250 pages each except for the 4th book which are the longest of them. So, I just finished the 2th book, and can't really say I have high hopes for the third book. But maybe I will get surprised, who knows?
