No WiFi, no distractions. No way out …

Agatha's husband has bought her a first-class ticket on the scenic six-hour train from Toronto to Montreal as a gift—a one-day writing retreat so she can get some serious work done on her new book, a highly anticipated follow-up to Agatha's runaway bestseller debut novel. The first-class car is the perfect place to be productive, with only a handful of other passengers, plenty of snacks and drinks, and beautiful views flying by outside the window.

But Agatha has other plans for her day out … plans that are unexpectedly derailed when the train breaks down in the middle of the frigid Canadian woods and one of Agatha's fellow passengers dies quietly in his seat. Soon, a pleasant morning in transit turns into a fight for survival against an unknown and unseen enemy. Will Agatha—or any of the passengers—make it out alive?

From international bestselling author Eva Jurczyk, 6:40 to Montreal is a claustrophobic, deceivingly bloody thriller that twists and turns until the very last page.

"An intense, claustrophobic nod to the Christie classic Murder on the Orient Express."—Library Journal
