Several titles in the Malcolm & Suzanne Rannoch series by Teresa Grant (pen name for Tracy Grant) have dropped in price at Kindle US. Confusingly enough, this series is a continuation of the Charles and Mélanie Fraser series, written as Tracy Grant, just with the names of the main characters changed, apparently as a result of a change in publisher. And to make it even more confusing, the books have not been published in the same order as they would have occurred chronologically. Luckily, there is a chronological list that covers most of the books on the author's website:
