The Gods Themselves, by Isaac Asimov

I love the artwork on old sci-fi book covers

I love "The gods themselves". Themes it explores are interesting and sci-fi parts are really clever and unique.

I read that so long ago, it only started coming back as I read the review. It's time for a reread. Thanks for posting.

For a long time it was my favorite book. It had something that captivated me at a level that no other book had before.

Had to drop it when it flipped to the alien universe, just couldn't keep interested.
