For fans of legendary pulp author H. P. Lovecraft, there is nothing
bigger than the annual Providence-based convention called the Summer
Tentacular. Horror writer Colleen Danzig doesn't know what to expect
when she arrives, but is unsettled to find that among the hob-knobbing
between scholars and literary critics are a group of real freaks: book
collectors looking for volumes bound in human skin, and true believers
claiming the power to summon the Elder God Cthulhu, one of their idol's
most horrific fictional creations, before the weekend is out. Colleen's
trip spirals into a nightmare when her roommate for the weekend, an
obnoxious novelist known as Panossian, turns up dead, his face neatly
removed. What's more unsettling is that, in the aftermath of the murder,
there is little concern among the convention goers. The Summer
Tentacular continues uninterrupted, except by a few bumbling police.
Everyone at the convention is a possible suspect, but only Colleen seems
to show any interest in solving the murder. So she delves deep into the
darkness, where occult truths have been lurking since the beginning of
time. A darkness where Panossian is waiting, spending a lot of time
thinking about Colleen, narrating a new Lovecraftian tale that could
very well spell her doom.
