The Midnight Eye Files: The Sirens

In Book II of the Midnight Eye series, PI Derek Adams embarks on what begins as a straightforward lost son case, but quickly spirals into the bizarre as he encounters mer-women, shape-changers, and ancient fisher cults on a remote island. As he attempts to escape back to the city, he discovers that magic and chaos are rampant, with an ancient god awakening and blood being the only solution to stop impending doom.
