"Jen Lowry has crafted a riveting page-turner. The story is told from the perspective of a female Christian detective, Heather Moody. I love how the author highlights the diverse personalities of the characters, and how Heather could walk her faith without preaching. This made her authentic and relatable. I read THE SUNDAY KILLER in two days. It's an adrenaline-raising suspense novel that will keep you on the edge until you finish the story." - Tish Bouvier, Poet and Cozy Mystery Author

"The perfect combination of cozy and creepy! With an adorable dash of romance. This book really has it all. I especially loved the wholesome Christian main character, and how her strong beliefs influenced her everyday actions-and how she approaches her job as a detective. I love seeing good, well-written, and exciting Christian fiction! We need more of this!" - Polly Harris, Swipe Right for Murder

"THE SUNDAY KILLER is a slow burn that grows into a roaring fire as the story develops! Jen Lowry excels in her characterization of our senior detective protagonist Heather Moody, to the point where the case of learning her backstory and character motivation is arguably just as compelling as catching the serial killer rampaging through Crystal Falls. Lowry also has a unique way of toeing the line well of writing a compelling, edgy crime story and firmly maintaining a clean reading experience. The book contains little to no profanity, and the depths of human depravity are explored in full but it's presented in even tamer of a way than any of the horror-adjacent visuals in Stranger Things. Sunday Killer is a masterclass in toeing the line between edgy and clean fiction. This book comes highly recommended for a reader wishing to find the rare book at the intersection of crime fiction and Christian values. Can't wait to see what Heather Moody (and by extension, Jen Lowry) does next! - Peter Fenton, Author of Abandon All Hope
