Daryl Wood Gerber’s whimsical cozy A Flicker of a Doubt blends the world of fairies and magic with the modern world. Anyone who reads modern fantasy novels knows that this is a very difficult thing to do effectively, and often times it comes off as childish or just simply difficult to believe. Fortunately, this is not the case here. This is the fourth book in the series, but not only are characters and setting clearly laid out for new readers, there is even a lovely index of who’s who and who’s what at the front. This is especially helpful when distinguishing between the cat named Pixy and the fairy named Fiona that both live with the main character, Courtney Kelly. The charming antics of Fiona and the other fairies, as well as their carefully worked in lore, accentuates and assists Courtney through her various adventures.
