More than a decade ago, six kids witnessed unspeakable horror. Not all of them lived to tell.

Riza is no longer that kid - troubled, angry, and filled with secrets. She's grown up, and when she stumbles upon an on-line forum about the shuttered Northern Michigan Asylum, she tries to pretend it never happened - not the years of experimentation, nor the strange midnight writings, and most of all, not the murders.

But someone wants her to remember.

Deaths shockingly similar to those that occurred in 1989 are happening again.

As the killings get closer to home, Riza is forced to face her past one last time.

Get lost in a chilling story of childhood secrets, unsolved murder, and a malevolent asylum for the insane.

Bitter Ground is the final installment in the Northern Michigan Asylum Series.
