Above, us, in the dark shadows of the outer solar system, there is the shape of something unknown, something unspeakable. It waits, it bides its time, and as the days of summer grow longer, so does its voice grow louder.

On the quiet island of Sarah Ann in the Pacific Ocean, home of the renowned Firmament Foundation, awkward teenager Eirian Calohan has come in search of the mystery of their father's recent demise. Instead, they are confronted with the stark contrast between languid life on the tiny island and an unspeakable cosmic horror.

Together with their new friends, they set out to unravel the truth surrounding the death of their father and to also uncover just what it is that the Foundation has reached out to in the dark eternal night of the distant void.
