Yes, I have read A Voyage to Arcturus and is it a rather unusual book. It has both Lindsay's faults and his strengths... brilliant ideas, meaty philosophical concepts, fascinating and haunting scenes... and, unfortunately, occasional patches of writing that pull one up short and simply make one stare that it ever made it past an editor. I mean, very clumsy writing. But only here and there, thank the Bonny Dew. It's a book well worth reading.
(And if you're ever able to come across a first edition of his Devil's Tor for a reasonable price... snatch it up! That one is ridiculously rare in its original printing... and it's very seldom seen print otherwise.....)
