I recently picked up this wonderful collection of H.G. Wells novels from Barnes & Noble. I was surprised to find that it was actually published by B&N back in 2006. It's a great-looking edition and it includes The Time Machine, The Island of Dr. Moreau, The Invisible Man, The War of the Worlds, The First Men in the Moon, The Food of the Gods, and In the Days of the Comet.
I've read the Time Machine and War of the Worlds before, both of which are obviously classics. But after picking up this edition I've read Dr. Moreau and am reading First Men for the first time. Dr. Moreau blew me away, since I'd never hear of it's storyline before. The way it's written really sucks you in, and you get a clear sense of abhorrence for what's going on on the island.
As for First Men in the Moon, it's got that great steam-punky/classic sci-fi feel that I love. It reminds me a lot of Poe's story of Hans Pfaall (read that right now if you haven't already). Wells' story is about a scientist that's developing a material which blocks gravity. It works in the same way that some materials block heat and some block light, etc.
So far I haven't looked at the other three novels, and I'm not familiar with them. I'm looking forward to reading them, and I'll let you know what I find out!
