For several years now, my favorite series of books has been the Honor Harrington series by David Weber. Crown of Slaves is a book set in the “Honorverse,” co-authored by Weber and Eric Flint. While Honor herself makes only a cameo appearance, it involves several characters introduced in the series (and in some of the Honorverse short stories previously written by Eric Flint.)
It was a good adventure, fun to read. I did spot what I felt was a major flaw in the thinking of a character who should have known better. It was necessary to the plot to have the character be gone for most of the story, and it would have been possible to do so even if the character’s thinking hadn’t been flawed. So it’s not a flaw that had an impact on the plot, but it’s just that when a character is supposed to be an expert, and he says there are three possible explanations for something, a fourth explanation should not be obvious to me.
Still, if you’re a fan of the Honorverse, it’s worth reading.
