Here’s the description of The Clinic.

“A superior, creeping psychological thriller taut with tension and drama.” —The Seattle Times

“Easily the creepiest setting for a suspense novel since the Overlook Hotel in Stephen King’s The Shining.” —BookPage

From the critically acclaimed author of Black Widows comes a thriller set in a remote rehab clinic on the Pacific Northwest coast, in which the death of a woman inside prompts her sister to enter the clinic as a patient in order to find the truth. Perfect for fans of Stacy Willingham and Tarryn Fisher!

Meg works for a casino in LA, catching cheaters and popping a few too many pain pills to cope, following a far different path than her sister Haley, a famous actress. But suddenly reports surface of Haley dying at the remote rehab facility where she had been forced to go to get her addictions under control.

There are whispers of suicide, but Meg can’t believe it. She decides that the best way to find out what happened to her sister is to check in herself—to investigate what really happened from the inside.

Battling her own addictions and figuring out the truth will be much more difficult than she imagined, far away from friends, family—and anyone who could help her.

Here’s the description of The Missing Witness.

“This latest installment will likely satisfy Quinn and Costa’s loyal followers and attract those curious about the interplay between public policy, law enforcement, and politics.” —Booklist

When a key witness goes missing, Quinn & Costa must find her before a killer silences her for good…

Detective Kara Quinn is back in Los Angeles to testify against a notorious human trafficker, finally moving past the case that upended her life. But when the accused is shot in broad daylight, the chaotic scene of the crime turns up few reliable bystanders. And one witness—a whistleblower who might be the key to everything—has disappeared.

After another person close to the case is killed, it’s clear that anyone who knows too much is in danger, and tracking down the witness becomes a matter of life-and-death. But as explosive secrets surface within the LAPD and FBI, Kara questions everything she thought she knew about the case, her colleagues and the life she left behind months ago.

Now with FBI special agent Matt Costa’s help, she must race to find the missing witness and get to the bottom of the avalanche of conspiracies that has rocked LA to its core…before it’s too late.
