When Dr. Marina Singh receives a 2 week old letter telling her that her lab partner has died of a fever in the Amazon and little else, she decides that she will be the one to go and search for answers. The pharmaceutical company she works for also wants answers, since her partner was there to find out the progress on a new fertility drug being developed by a rogue scientist heading up the research there. 
 This was a fascinating read encompassing everything from mystery to science to self-discovery. I could barely put this book down. There was a new twist and turn with every chapter! Only a couple of minor hiccups at the end that I could have done without. My only real complaint would be that it ended too abruptly! I wanted to see where the characters' stories continued to go. Maybe a sequel is in order?
