Reddit reviews Evolution's Shore

This isn't exactly what you asked for but "On Evolution's Shore" and it's sequel (and short stories) by Ian McDonald are amazing and criminally under-known. It has to do with people investigating a crisis in Africa caused by an alien "spore" crashing into jungle and terraforming it into "Chaga." I don't want to spoil things but, the Chaga isn't as hostile as is first believed (the gov version is that it's like the Chtorr). It tailors itself to maximize the habitat volume of it's occupants and allows them to make biotech. It eventually pits humans using Chaga derived / hybridized tech against "Mech" Tech. Sort of like the Yuuzhan Vong.
