In The Garden Of Iden by Kage Baker. 329 pages.
I'd seen a lot of people praising Kage Baker's "Company" novels so I thought I'd give this first one a try. It wasn't quite what I expected - I'd got the impression somehow that "The Company" was something like Glen Cook's Black Company, a military unit of some sort, but I was wrong.
The idea behind the books is an interesting one - a huge company which sends immortal cyborgs back in time to rescue plants, animals and artworks which would otherwise be lost forever, but which is so big that no-one's really sure who's running it or what it's ultimate purpose may be. But the actual story, though it introduces that idea well, seemed to have little point to it in my opinion. The time-travellers can't alter events either and much watch while events unfold which they know will end in tragedy but which they can't prevent. If anything it reminded me of the historical stories from classic Doctor Who and I never much cared for those.
The main character, Mendoza, is a new recruit into the Company and she is sent to England under Mary Tudor to save various beneficial plants in a garden there. Mendoza is a sympathetic character, and I liked the story well enough, but it didn't seem to really go anywhere. I may give the author another try though.
