Amazon lists a new £3.99 ebook edition of The Xothic Cycle by Lin Carter, for publication 26th March 2020. It’s from Gateway, ebook re-publishers of the Gollancz yellow-covers of yesteryear. It’s possibly not completist, though, as the blurb calls it the first such book…

This is the first collection of Lin Carter’s Mythos tales; it includes his intended novel, The Terror Out of Time.

“First” of two or three? As such I suspect this is not to be confused with the Chaosium title The Xothic Legend Cycle: The Complete Mythos Fiction of Lin Carter, edited by Robert M. Price. If you can’t wait for the 2020 ebook, then the Price collection can currently be picked up in paperback for £10 inc. shipping, and has an introduction by Price to each story. According to a Table of Contents kindly posted by the late W.H. Pugmire it doesn’t, however, include the “intended novel, The Terror Out of Time” — which the ebook apparently does.

Was Carter any good as a Mythos writer? It’s not all that easy to quickly find out. He was a pro, and yet S.T. Joshi has little to say about Lin Carter as a fiction writer (rather than a scholar and critic) in the book The Rise and Fall. One has to snuffle around in the sparse online comments to get a sense that Carter was post-Derlethian in his free-wheeling and name-spawning approach to the Mythos. I don’t get the sense he was going reverently back to the master and trying to fill in the gaps, in manner that was both relatively seamless and stylistically congruent.

W.H. Pugmire was rather more helpful in giving an opinion, remarking in an Amazon review of the Price book that…

The writing in this book may not be first class, but dang if this isn’t an amazingly FUN book to read.”

He also implied there was no attempt to mimic Lovecraft, with Carter’s…

style being that of a story-teller, plain and simple. I find the writing style in this book extremely pleasant, and the narratives flow easily.

Thus it sounds like a fun book for completists. But don’t expect to encounter Lovecraft’s style, or a Mythos with the Derlethian accretions chiselled off.
