Helena Pelletier has a loving husband, two beautiful daughters, and a business that fills her days. But she also has a secret: she is the product of an abduction. Her mother was kidnapped as a teenager by her father and kept in a remote cabin in the marshlands of Michigan’s Upper Peninsula. Helena, born two years after the abduction, loved her home in nature, and despite her father’s sometimes brutal behavior, she loved him, too...until she learned precisely how savage he could be.

More than twenty years later, she has buried her past so soundly that even her husband doesn’t know the truth. But now her father has killed two guards, escaped from prison, and disappeared into the marsh. The police begin a manhunt, but Helena knows they don’t stand a chance. Knows that only one person has the skills to find the survivalist the world calls the Marsh King—because only one person was ever trained by him: his daughter.

Eighteen years ago tragedy struck The Refuge cult in northern Minnesota. Forty people committed suicide and the entire compound burned to the ground. At just thirteen, Clare was the sole survivor found wandering miles from the encampment, hands blistered, memories of the horrific event wiped from her mind.

Now a sociology professor and liaison to the FBI specializing in cults, Clare has fought to put the past behind her. She has a successful career, a quiet home, and is deeply in love. But intrusive memories and fear of inheriting her cult-leader father’s mental illness threaten to strangle Clare’s budding life when she receives a call from the past. A call informing her a woman has been found claiming to be her sister Shanna—a sister she long thought dead.

Wracked with guilt but determined to prove herself to the sister she thought was lost, Clare returns to her hometown only to be stalked by a threatening stranger and haunted by hallucinations which seem all too real—hallucinations that plagued her father as well. Before long Clare begins to question what is real as the past overshadows the present and memories return that should’ve stayed forgotten.

I just finished the Soldier Son Trilogy, and started my first Louise Penny novel

It looks like you might be able to watch some free episodes of Cadfael here.

Another Peters I love is Elizabeth (pen name of the late Barbara Mertz), author of the funny Amelia Peabody Egyptian archaeology mysteries. From the first novel, Crocodile on the Sandbank, where Amelia first goes to Egypt as a single woman to the 20th, The Painted Queen, finished by Joan Hess after Peters died in 2013. Not only are they fun and suspenseful, but they provide insight into ancient history and archaeology in the late 19th and early 20th centuries.
