This was an "I can't go to to sleep until I finish" book. I was completely gripped from start to finish.
But I was disappointed with a few of the plot choices. Romance-wise, she chose not to use the only really sexy character she created. The love interest she chose for Gil was...puzzling. It made no sense to me at all.
And I was disappointed that, as a historian, the author never addressed the more complex issues surrounding the choice to exterminate a native civilization (even one that is trying to exterminate you).
