"If the quality of her debut crime novel Too Dark to Sleep is anything to go by, Dianne Gallagher's name will spread quickly in crime fiction loving circles. This is a fine debut novel, and in Maggie Quinn, Gallagher has created a true one-off with as many layers as an onion... More please." -Crime Fiction Lover 5 Stars

"An outstanding, suspenseful novel you don’t want to end. Maggie is a character to cheer for, be afraid of, and feel sorry for. We can only hope that this isn’t the end of Maggie." Reviewed by Sherri Nemick for Suspense Magazine
"This is a noir thriller with great depth of character... I was on the edge of my seat. I was totally confused and I loved it. Was Maggie right about the killer? Who would win the war? Could Maggie hold herself together and push back the darkness long enough to solve it? I even gasped in surprise a couple of times.By the time I finished, I felt washed in Maggie's darkness. There's no real redemption in this story, but that's okay; nobody is looking for redemption....Sink into the darkness with Maggie. It's an uncomfortable place to be, but I couldn't put it down."

"Too Dark to Sleep is a hard-core, psychologically tense crime fiction... shades of Mickey Spillane and other broken investigators who take the reader for a quick spin in a fast car. The dark is every much a character as the people who work with or against the solving of crimes... Do not start reading at bedtime because one will have to read all night." - IndieReader 5 stars
"In the vein of Jeffrey Deaver thrillers... Gallagher's fast-paced plotting and psychological hairpin turns keep the reader guessing... and wanting more. Couldn't put this one down and can't wait for the next in the series! Two thumbs up!"
"A darkly ominous crime thriller... terse narrative and crisp dialogue... tautly written but richly detailed..." - Kirkus Reviews
"Maggie Quinn is an incredible main character, multifaceted and strong despite setback after setback... a spine-tingling book that readers everywhere will adore." - Reviewed by Alice DiNizo for Readers' Favorite
"Chicago noir aficionados will love Dianne Gallagher’s debut novel, Too Dark to Sleep... I didn’t want to put it down. I was fascinated by Gallagher’s depictions of the subcultures of Chicago police detectives, the Cook County Medical Examiner’s Office and Stateville Penitentiary. It’s a world of clout-influenced decision making, where who you know, nine times out of ten, trumps what you know. After all, that’s the Chicago Way!" - Richard Reeder, author of Chicago Sketches
"Too Dark to Sleep brings a wonderful twist to an often clichéd genre, enabling the reader to dive heart and mind into Maggie Quinn's life. The book is chock-full of tension, with a lot of questions that are satisfyingly answered at the end. However, there is enough left to the imagination to leave the readers begging for more. Too Dark to Sleep is a must-read for anyone looking for an exciting story that keeps the reader guessing and hungry for answers." Reviewed by Starza Thompson for Windy City Reviews
