Query: Jack Randall saved this series...

... and his absence killed it. When I read the first book in this series, A Dragonfly in Amber, I was happily suprised that it wasn't a run-of-the-mill, formulaic romance. The characters were shockingly three-dimensional and the antagonist was, well, a bad guy with a face behind the black moustache, so to speak.Well, sequels have been disappointing, not least Drums of Autumn. Brianna has the personality of a paperdoll compared to her mother, and unfortunately a great deal of the book revolves around her. Likewise, her love interest is only slightly more charismatic.In summary, don't miss the first book of this series but don't bother with the rest.
