I'm quite enjoying this, although I'm not sure how to explain why. Or even why I'm enjoying it, really. I need to write something down, though, or I'm going to be trying to talk about intelligent spiders later when I go out with some friends, and I really don't think they'd understand why it's so cool that they're at war with the ants. Big spiders. Big ants. Plus unsuspecting humans! Sort of. The ants remind me of the armies of Mordor.
I feel like it's a cross between David Brin, Vernor Vinge, and Peter Watts. I don't actually like spiders in any way, but somehow they make for interesting alien intelligences. Maybe the creepiness helps instill that sense of alienness? Not sure.
My following comments aren't that spoiler-worthy, but just in case you don't want any more info than I've already provided (or you just don't want to hear about spiders), I'll put them in spoiler tags.
Now I'm going to illustrate why I was so tempted to take advantage of that 50% off Kobo sale to buy the ebook. [I may post something later about some of my other purchases.]
My copy of Forever Amber (picture Lydia Bennett if she had lived 150 years earlier and had had no one to fetch her from London) is 972 pages and about 4.5 cm thick. Children of Time was only a few mm short of that at exactly 600 pages. It wasn't that heavy, but it just took up so much room!
