Catherine Littlefield was raised in a seaside New England town haunted by whispers of arcane lore that remained tantalizingly out of reach to a daughter of well-to-do Baptists. But when her studies at Barnard College in New York lead to an encounter with a secret society, she is offered access to the knowledge she has always sought...if she can pass a test. Dispatched to California to infiltrate the occult world of a rival magician—a pioneering rocket scientist with ties to the apocalyptic Starry Wisdom Church—Catherine soon discovers that she’s not the only one spying on Jack Parsons. A fledgling government agency devoted to the investigation of weird science in the aftermath of the World War II has assigned a pair of hard-nosed agents to gather information on her target, whose experiments with sex magic and eldritch artifacts are approaching a cosmic crescendo. Drawn into the volatile chemistry of Jack’s inner circle and tempted with knowledge and power, Catherine must determine what’s at stake for a world threatened by dark forces and decide where her true loyalties lie.

The Red Equinox has dawned, and the old gods who have slept for aeons are stirring. Urban explorer and photographer Becca Philips was raised in the shadow of Miskatonic University, steeped in the mysteries of her late grandmother’s work in occult studies. But what she thought was myth becomes all too real when cultists unleash terror on the city of Boston. Now she’s caught between a shadowy government agency called SPECTRA and the followers of an apocalyptic faith bent on awakening an ancient evil. As urban warfare breaks out between eldritch monsters and an emerging police state, she must uncover the secrets of a family heirloom known as the Fire of Cairo to banish the rising tide of darkness before the balance tips irrevocably at the Red Equinox.

WELCOME TO THE WADE HOUSE WHERE THE DOORS OPEN YOU Two years after the Starry Wisdom Church unleashed their dark gods in Boston, Becca Philips is trying to put the events of the Red Equinox behind her when Agent Brooks tracks her down in Brazil. Becca has been summoned back to Massachusetts by SPECTRA, the covert agency entrusted with keeping cosmic horrors at bay. Her special perception and skills are requested at the Wade House—a transfiguring mansion of portals to malevolent dimensions. Becca would like to refuse, but Brooks believes her estranged father may be lost between worlds at the abandoned estate. As Becca struggles with grief and forgiveness, she joins a team of explorers uniquely suited to decode the secrets of the strange house in the black snow. But what secrets do her companions harbor? And who among them will take theirs to the grave?

THE CHILLING FINALE OF THE SPECTRA FILES TRILOGY The Wade House has been reduced to ash, but the dreams that plagued Becca Philips and Jason Brooks when they slept in that abomination continue to haunt them. After years of facing trans-dimensional monsters in the service of SPECTRA, a few lingering nightmares are to be expected. But when Becca starts singing in her sleep—an ancient song that conjures dreadful things from mirrored surfaces—she fears that the harmonics she was exposed to during the Red Equinox terror event may have mutated not only her perception, but also her voice. It’s a gift—or curse—that she shares with a select group of children born to other witnesses of the incursion. While a shadowy figure known as the “Crimson Minstrel” gathers these children to form an infernal choir, something ancient stirs on the ocean floor. And Becca, hearing its call, once again finds herself running from an agency she can no longer trust, into the embrace of cosmic forces she can barely comprehend.
