He was trained to protect. She was never meant to be his to save.
Cybersecurity specialist Ava Sinclair lives by one rule: trust no one. After uncovering a secret file buried inside a massive data breach, she becomes a target---and the only person standing between her and a bullet is a man she doesn't know or trust.
Rob "Grits" Grimes, former Navy SEAL turned operative for Hamilton Investigation & Security, has one mission: protect Ava at all costs. She's brilliant, guarded, and nothing like his usual assignments. But when an ambush forces them off the grid, Grits realizes the threat is more than a hit job---it's a conspiracy that could take down powerful players, including someone inside his own agency.
As danger closes in and Ava edges closer to the truth, sparks ignite between them. But the closer Grits gets to her heart, the harder it becomes to keep his own secrets buried.
Someone wants her silenced.
He's the only one standing in their way.
But protecting her could cost him everything.
Sheila Kell writes about the romantic men who leave women's hearts pounding with a happily ever after built on memorable, adrenaline-pumping stories. Or, (since her editor tries to cut down on her long-windedness) simply "Smokin' Hot Romance & Intrigue." Her debut novel, HIS DESIRE (HIS Series #1), launched as an Amazon #1 romantic suspense bestseller and Top 100 overall, later winning the Readers' Favorite award for best romantic suspense novel. As a Southern girl who has left behind her days with the United States Air Force and as a University Vice President, she can usually be found nestled in the Mississippi woods, where she lives with her cats and all the strays that magically find her front door. When she isn't writing, you can find Sheila with her nose in a good book, dealing with the woodland critters who enjoy her back porch, or wishing she had a genie to do her bidding. Sheila is a member of Romance Writers of America.
