2020 SF, last of its trilogy. This time Thorn is mucking about with
time.
Well, there's a little more uncertainty about what to do next
than in book 2, but the only difficulties are in working out what to
do, not in actually doing it. Most of the characters this time don't
even have names, because this story is all about Thorn and not really
about anyone else. (As if the first-person narration weren't a
giveaway.)
Also we get Baby's First Gun Control Lecture and even as someone
broadly not in favour of private firearm ownership I found it not only
naïve and preachy but very clearly rooted in the author's own time
rather than in the context of the science-fictional setting. (Ah well,
at least this will annoy the sort of reader who would otherwise be
ready to praise any power-fantasy.)
There's also lots of time travel, which is suddenly easier than it was
last time, and nobody seems particularly worried about paradoxes. Hey
ho.
Even if you enjoyed wasting your time with book 1, as I did, don't
bother with 2 or 3. Still, it did clear my palate after a certain
Hugo-nominated novel; I finished this, and I didn't finish that.
