Gayle Lynds on DEAD OF WINTER

New York Times best-selling author of The Assassins

“With riveting suspense and vivid details, Dead of Winter by Sherry Knowlton brings the towns and forests of Southcentral Pennsylvania to vivid life as cultures and beliefs clash in a searing tale of murder, love, and communal fear.  From flying drones to police investigations and legal wrangling, Dead of Winter will keep you guessing and glued raptly to your reading chair.” 

Midwest Book Review by Alma Bonds on DEAD OF WINTER

An organization committed to promoting literacy, library usage, and small press publishing

“Ms. Knowlton is a fine writer, who writes beautiful prose as good as that of much of our finest fiction … The book is an intriguing, suspenseful story which grabs the attention of the reader from the very first page … Alexa Williams again proves a formidable heroine in this suspenseful tale of international corruption and hatred.”

J. J. Hensley on DEAD OF WINTER

Author of Bolt Action Remedy and Record Scratch

“Sherry Knowlton brilliantly weaves contemporary issues into a riveting mystery that will stick with you long after the last page is turned. In Dead of Winter, the reader can sense a fuse has been lit and is burning closer to a rural Pennsylvania town that is on the brink after a series of deaths appear to lead back to the normally tranquil setting. While addressing xenophobia, racism, and America’s complicated history, Dead of Winter is the novel we need and the story we want.”

Author Matty Dalrymple on DEAD OF WINTER

Author of the Lizzy Ballard Thrillers and the Ann Kinnear Suspense Novels and Shorts

“In Dead of Winter, Sherry Knowlton examines the explosive combination of ignorance and fear that results in hate and violence.


Knowlton uses her familiarity with both small town South Central Pennsylvania and the wilds of Africa to good advantage in her fourth Alexa Williams novel. Her use of drone technology to set up the discovery of the crime in which Alexa will find herself caught up is clever.


Knowlton skillfully weaves together two story lines. One involves the flight north of two Virginia slaves in the years leading up to the Civil War, with Pennsylvania representing the land of freedom and equality. One involves current-day racial tensions, where the same ground is the site of racially motivated intimidation tactics and terroristic threats.


A thought-provoking novel dealing with issues that are as important now as they were at the time of the Underground Railroad."

"Knowlton weaves a compelling tale, and the threads become tighter as the plot progresses. A suspicious suicide of a powerful politician takes on new meaning when Alexa Williams’s investigations uncover corruption at the heart of the fracking industry.  And when she becomes the target, the tension ramps up to a thrilling climax. Highly recommended."

Heroine Alexa Williams resists intimidation to battle evil at the highest levels of Pennsylvania government and commerce. Spurring her on is a love for the environment and for a friend whose daughter's cancer is caused by fracking. Here is a spellbinding yarn jerked straight from today's frightening headlines."

Steve Berry on DEAD OF SUMMER

New York Times and #1 International Bestselling Author

“Alexa Williams is a sassy, alpha-female heroine.  The plot is knotty, lots of will-she or won’t she, all woven into an intense battle of wits that heats up every page.  While reading, I could almost see the credits rolling for the movie." 

Melissa F. Miller on DEAD OF SUMMER

USA TODAY bestselling author of legal thrillers and romantic comedic mysteries

“Fans of Sherry Knowlton's "Dead of Autumn," will find summer to be an equally deadly season. "Dead of Summer" is a riveting, suspenseful read as it crosses time and space while Alexa unravels a murder. Residents of Central Pennsylvania will particularly enjoy the authentic, local touches.” 

Heidi Ruby Miller on DEAD OF SUMMER

Author of the Ambasadora series

Sherry Knowlton's follow-up book is just as edgy and engaging as Dead of Autumn. Continuing with the seasonal theme, Dead of Summer captures the season in multiple times and places, especially present day southcentral Pennsylvania, where the people are intriguing and real. Alexa Williams reprises her role as lawyer/amateur sleuth/women's rights activist and reminds us that smart women can still have emotions without sacrificing strength. The plot issues concerning human trafficking were powerful. I look forward to seeing what Sherry does with the next installments of the series.”

Mark Leggatt on DEAD OF SUMMER

Author of International Thriller 'Names of the Dead'

“I enjoyed this immensely, it’s an atmospheric, twisting tale of deceit and discovery, in evocative Americana settings. The main character is drawn into a murky world of sex-trafficing, charismatic characters, both young and old, where the good and bad are hard to define, until the chilling resolution. Highly recommended.  An atmospheric, twisting tale of deceit and discovery, in evocative Americana settings.”

Val Muller on DEAD OF SUMMER

Author of the Faulkners Apprentice and Corgi Capers

"Like the first book, I enjoyed Dead of Summer. The author’s selection of detail helped me imagine that I was there with the characters, and by the end Alexa once again felt more like a friend than a character. I knew about her coffee and yoga habits, her family dinner on Friday night… It helped that Alexa seems as tied to her giant and lovable dog as I am to my corgis.


With all Alexa has been through, she seems to become skeptical of almost everyone (especially guys), and since we see much of the story through her eyes, her skepticism helped keep me guessing. I especially enjoyed that the thrills kept coming, even after I reached what I thought was the denouement.


The Woodstock story was entertaining, and I kept waiting for the connection to modern day to be made–which it was, adding to the tension of Alexa’s situation. All in all, I enjoyed this thriller."
