Dark Currents fits right into the current trend of urban fantasy and supernatural mystery books with spunky female protagonists, only the urban part is missing. An enthralling story of accidental death and mild mayhem set in the rural midwest in a town, not quite like your own, because of the presence of Yggdrasil II and the Norse Goddess Hel. There are the obligatory werewolves and vampires, but the main character is a half-demon police irregular, who serves as Hel's liason between the eldrich community and the mundanes.
Dark Currents caught my interest enough to stay up after bed-time reading, but couldn't quite earn the elusive 5th star. While nowhere nearly as sexually explicit than Carey's earlier works, there is enough discussion of desire that I would hesitate to give this book to a younger reader.
