Kathy Ryan’s work as an occult investigator often leads her to the outskirts of society, law, and even reality…
Knowing that other dimensions exist is one thing. Venturing into them is quite another. In the course of its experiments, Paragon Corp—a government-sourced theoretical physics research institute—has discovered a supposedly empty alternate world.

Then the scientists disappear. Kathy Ryan is hired to make her first foray into an alternate dimension in order to locate the team, bring them back, and close the door for good. Instead, she discovers that this supposedly dead city may be nothing of the kind. Her rescue mission has become a terrifying race to prevent the potential destruction of the boundary between two worlds—before mayhem reigns over both…

INSIDE THE ASYLUM (A Kathy Ryan Novel Book 3) (May 2019, Kensington Books)
From “master of cosmic horror” (Library Journal) Mary SanGiovanni, comes the latest terrifying novel featuring occult specialist Kathy Ryan . . .
A mind is a terrible thing to destroy . . .
Kathy has been hired to assess the threat of patient Henry Banks, an inmate at the
Connecticut-Newlyn Hospital for the Criminally Insane, the same hospital where her brother is housed. Her employers believe that Henry has the ability to open doors to other dimensions with his mind—making him one of the most dangerous men in modern history. Because unbeknownst to Kathy, her clients are affiliated with certain government organizations that investigate people like Henry—and the potential to weaponize such abilities.
What Kathy comes to understand in interviewing Henry, and in her unavoidable run-ins with her brother, is that Henry can indeed use his mind to create “Tulpas”—worlds, people, and creatures so vivid they come to actual life. But now they want life outside of Henry. And they’ll stop at nothing to complete their emancipation. It’s up to Kathy—with her brother’s help—to stop them, and if possible, to save Henry before the Tulpas take him over—and everything else around him.

For generations, folks have come to the Door seeking solace or forgiveness.

Three days later, their wish is answered—for better or worse.
Kari is a single mother, grieving over the suicide of her teenage daughter. She made a terrible mistake, asking the powers beyond the Door to erase the memories of her lost child. And when she opened the Door to retrieve her letter, she unleashed every sin, secret, and spirit ever trapped on the other side.
Now, it falls to occultist Kathy Ryan to seal the door before Zarepath becomes hell on earth . . .

His old love, Mia Dalianis, has left him a voicemail message begging him to come back, if not for her, then for the daughter Jesse never knew he had. Jesse needs to go back. He’s been running for a long time — from relationships, friendships, everything he is afraid of and feels guilty over. He realizes that the nightmares will never stop until he goes to Thrall. With help from Nadia Richards and some old surviving friends from Thrall, Jesse intends to find his daughter or die trying. He goes looking for redemption, but what he discovers about his old hometown may destroy him and everyone he’s ever cared about.
