Ground Zero

2019

Ground zero, noun: the center or origin of rapid, intense, or violent activity or change. Heat, humidity, and homicide are things veteran detective Sawyer Key expects to encounter on his first day with the Savannah Police Department, but the hostile reception from his new partner catches him by surprise. Sawyer isn’t a stranger to heartache and recognizes that Royce Locke is a wounded man who’s reeling from a devastating loss. Relentless and patient in all things, Sawyer is determined to make the new partnership work. Savannah, Georgia is known for her quirky people, oak trees draped in Spanish moss, and antebellum architecture. Beneath the Southern charm and hospitality, festering hatred and violence is soaring with the summer temperatures. Locke and Key find themselves at the epicenter when their first case involves the death of a former shock jock who appears to be the victim of vigilante justice. Opposites in nearly every way, the two detectives set aside their differences to take back their city and restore law and order. From this reluctant truce, an intense attraction grows that will either tighten or shatter their tenuous bond. Falling for his partner spells inevitable disaster, but Sawyer’s always been a sucker for wounded things. Sawyer could be the key to the life Royce has always wanted, if he’s brave enough to trust him. The fuse is lit, the clock is running, and the zero hour is upon them. Tick tock. Ground Zero is the first book in the Zero Hour series, which follows Locke and Key’s investigations and evolving relationship. Ground Zero has a happy-for-now ending with no cliffhanger. It contains mature language and sexual content intended for adults 18 and older.

Devil's Hour

2019

Devil’s hour, noun: the hour when the demon or devil who leads hell is at its strongest. Born on the wrong side of the tracks, Royce Locke is no stranger to scrapping and fighting for the things he wants. What he desires most is Sawyer Key—his partner on the force and the man he’s falling in love with. After asking Sawyer to take a chance on him, Royce will need to back up his pretty words with fearless action instead of being his own worst enemy. Someone is harassing the mayor of Savannah, and Locke and Key are tasked with finding out who. The investigation quickly takes a twisted turn, leading them to an enemy who thinks purification by fire is the only way to save the city. Scarier than The Purists’ elusiveness is their ability to turn public opinion in their favor, creating unrest and threatening anarchy by fanning flames and fear. When you play with fire, someone is bound to get burned. When menace becomes murder, the two detectives will race the clock against the devil to save their beloved city from becoming a raging inferno. Royce will need to draw on his grit now more than ever if he hopes to realize the dreams that are finally within reach. The rag is lit, the Molotov cocktail is tossed, and the zero hour is upon them. Challenge received and accepted. Devil’s Hour is the second book in the Zero Hour series, which follows Locke and Key’s investigations and evolving relationship. This is a series that must be read in order. Devil’s Hour has a happy-for-now ending with no cliffhanger. It contains mature language and sexual content intended for adults 18 and older. Trigger warning: Part of the storyline involves coming to terms with a friend’s suicide, which may be difficult for some people to read.

Zero Divergence

2020

Zero Divergence, noun: no deviation from a course or standard. After a key piece of evidence goes missing, a suspected serial rapist and killer evades prosecution. More than Royce Locke’s reputation is on the line when his investigation into the failed chain of custody suggests Franco Humphries might’ve had inside help. There’s no one Royce trusts more than Sawyer Key to help him right a wrong and uncover the traitor in their midst, but can they do it before the Savannah Strangler strikes again? Relentless plus fearless equals flawless. Sawyer and Royce have come full circle—from hostile strangers to best friends and lovers. Neither a sniper’s bullet nor an arsonist’s fire could keep them apart, but what about a psychopath hell-bent on revenge? The stakes are high, and there’s no turning back now because the zero hour is upon them. Tick tock. Zero Divergence is the conclusion to the best-selling Zero Hour series, which follows Locke and Key’s investigations and evolving relationship. This is a series you MUST read in order.
