A thrilling adventure on the other side of the Cthulhu Mythos: as the Old Gods awaken...

Like other students at Miskatonic University, Jenny Parrish worries mostly about passing her finals and getting a graduate assistantship.

Then an unexpected letter arrives from her great-aunt Sylvia, inviting her to spend the holidays and celebrate a mysterious Festival at the family mansion in the old port city of Kingsport, where Jenny has never been--the home her mother fled at the age of eighteen, never to return.

Once she reaches the ancient mansion, Jenny finds herself in the midst of a tangled web of archaic secrets, eldritch lore, and hidden struggles that pit the servants of the Great Old Ones, the ancient gods and goddesses of Earth, against a terrifying and relentless foe.

At the centre of the web stands the treasure Jenny's family has guarded for centuries, a talisman of supreme power forged in the lost land of Hyperborea: the Ring of Ebon.

But the Ring is lost--and the quest to find it and keep it out of the hands of the enemies of the Great Old Ones will send Jenny on a journey beyond the borders of the world to dread Carcosa, the city of the King in Yellow...
