It's taken me a little while, but Del Rey finally makes it into my own personal top tier, and I take back any disappointed noises I may have made on the grounds that van Vogt has fired off at least a couple of duds, and even Simak managed one. Of Del Rey's novels, most that I've read have been juvies - those being what I tend to find in second hand book stores for some reason - and although they've been good or even great, it's difficult to get the measure of a writer keeping at least some of his schtick reigned in for the sake of a particular audience; and then there's Day of the Giants which is fantastic, and Nerves which isn't. The Best of mostly comprises short stories which first appeared in Astounding, Galaxy, Unknown Worlds and the like, and this seems to be where he really shines.
It may be the ideas, which often pack a genuine punch of astonishment even after a half century of fucking everything having a twist ending; or it could be the telling, which is fresh, and engaging, and didn't seem loaded with reminders of having been written prior to the invention of teenagers - Superstition, for one example, reminded me of Stephen Baxter on more than one occasion. Whatever it may be, Del Rey does it with a lightness of touch that makes it seem easy and compels you to keep reading in much the same way as did Philip K. Dick, where the poetry is shaped in what is described rather than given as description in its own right.
This being said, I encountered a lull around half way through which picked up with the aforementioned Superstition, although this may have been down to me and my daily circumstances rather than to anything Lester wrote. However, focusing on his strengths, he seems at his best when jamming something which shouldn't work into the middle of an otherwise traditional story, then forcing everything else into line. If this sounds familiar, I suspect Superstition's apparent reference to the similarly awkward A.E. van Vogt may not have occurred just in my imagination:
'This story sounds like something from those papers of Aevan's we found. A fine mathematician from before the Collapse, but superstitious like you. He actually believed in mind-reading, clairvoyance, and teleportation!'
The story - some unknown force instantaneously throwing a number of spacecraft across two-hundred thousand light years - actually sounds like the work of A.E. van Vogt, here presumably rendered as A.E. van, then just plain Aevan in case that wasn't obvious; and what follows slaps the reader about the face with the similarly inexplicable whilst simultaneously pondering on religious models of reality with the sort of conviction that Dick managed in a few of his later books. Related themes of theology and morality are revisited in For I Am a Jealous People, The Seat of Judgment and Vengeance is Mine, each of novella length and as such extremely satisfying. I was mostly expecting well-executed tales of robots and rockets, but Lester Del Rey obliges you to consider what you're reading.
This comes just after some online observation made about how he could be a bit of a twat in real life, but the same has been said of Harlan Ellison - one of Del Rey's proteges - so I don't really care.
