I won’t spoil it by mentioning the titles, but I’ve read two and they both end in psychic phenomena and so forth. They had their merits, but I didn’t like the endings that much. Are there any that are more straightforward sci-fi?
His short story collections come to mind. The space station ones and the moon landing ones.
Oh yeah, and the tales from the Whirt Hart shorts.
Still, it’s his style, more or less, to get all wavy about cosmic topics. Even in many of his shorts or even if it’s simply in passing. It’s Clarke’s schtick.
Rendesvous with Rama steers clear of the mystical mumbo-jumbo, as I recall.

I haven’t read it for years, but a couple of things that I remember from it were his accounts of what we would now call a PDA, plus the internet: I’m now living in the future that made me say “cool” when I read about it in a sf novel.
And stay away from Cradle. I got through the Rama books but I could not slog through Cradle. Gentry Lee just lays the religous stuff on a bit too thick.
It’s only a little more annoying then ACC’s complete hostility to religion in some of his later books.
