The coastal town of Dorsal Finn is no stranger to the fantastic and the bizarre. A dark heart beats beneath its cobblestone skin and the rhythm is a beacon for all things devious and evil. Only its reluctant sentinel, Beatrice Beecham, keeps the town free from the terrible entities that it attracts.

Now Dorsal Finn has four new visitors. They look like a regular gang of youths, yet they are anything but human. Masters of manipulation and skilled in deception, these beings have their own agenda. Their tools to move their plans forward include an esoteric device and a terrifying cosmic creature with deadly intent.

And, unless she can stop them, the ritual sacrifice of Beatrice’s best friends.
