The Lost World, a nearly perfect adventure story.

The characters it involves are excellent and, surprisingly, are the most entertaining thing in this book. The relations between them, the variety of reactions to situations, etc... it's all good.

The quest for the lost world in itself is quite exciting as well, and you really feel immersed in the party.

If I had to point out a few things I liked less, that might be the fact that problems often find simple solutions (view spoiler)[Cutting the tree to make the bridge... we all saw that coming didn't we ? Escaping through a cave, that was effortless, and as for danger : let's just shoot our way through and destroy everything (well, almost) ! But the pterodactyl twist, that was pretty cool, as well as the unromantic ending (hide spoiler)].

In the end, the lost world they visit is very interesting but lacks a little something to make it crazy enough for me (the fact that I'm a big fan of Jurassic Park might have something to do with that), still I highly recommend this classic.
