This book opened strong but lost a bit of steam along the way--a trend I found continued in the series. I immediately sympathized with the protagonist, who I felt struck a good balance between vulnerability and strength as she dealt with a very bad situation that although set in the past was one that any modern woman could relate to. I was still onboard as the main plot tension point took a slightly more fantastical and mysterious shape, however this is where things got a little messy for me. There seemed to be a lot of running around in the jungle for no apparent reason and some romantic tensions that didn't feel totally authentic. Still I enjoyed this novel, which was quite creative and unexpected in its blending of science, historical fiction, and romance.
