Yawn. This one is early-ish Roberts, and I just really couldn't get into it (I was about 40% of the way done when I gave up). I didn't find either the hero or heroine likable, or even interesting, and I saw zero chemistry between them. The trek across Madgascar was just tedious, and the fact that the bad guys caught up with them at every turn seemed improbable. The historical subplot/search for the jewels seemed like it should have been fascinating, but it just didn't work.
