State of Wonder

I've read State of Wonder by Ann Patchett which is set in the Amazonian jungle. An eccentric scientist, Annick, working for a big drug company is developing a drug to prolong female fertility. Another scientist, Anders, from the company is sent down to check on her progress as Annick hasn't communicated with the company for a long time. The company later receives a lettergram from Annick saying that Anders has died. So another employee, Marina, is sent down to find out more about Anders' death and the progress of the drug development. It is a fairly slow story and didn't grip me. There are moments of "adventure" but I think the scenario painted is improbable, but of course it is a story. 31/2/5
