Books set in the jungle?

I'm looking for adventure/mystery/suspense books set in the jungle (rainforests, deep jungle) . I had read 'Amazonia' by James Rollins, 'The Codex' by Douglas Preston, 'White Cargo' by Stuart Woods, 'Congo' by Michael Crighton, and I loved all of them. Please help me with some other great titles that I can read. Thanks a LOT.
