A tough bear shifter bodyguard undercover in a coffee shop + a curvy barista with an adorable 5-year-old + a deadly shifter assassin = a scorching thrill ride of a romance!
Tough as nails and hard as steel, Derek Ruger has spent his life in dangerous parts of the world, and has the scars (emotional and physical) to show for it. But this is his most difficult assignment yet: going undercover in a coffee shop to protect a curvy witness, who happens to be his fated mate!
Single mom Gaby Diaz is just trying to make ends meet, working as a coffee shop barista while taking night classes, caring for her 5-year-old son, and supporting her widowed mother. Then she witnesses an armed robbery, and now she’s being hunted by an assassin and protected by a hot, gruff bodyguard who just might be able to coax Gaby into opening up the heart she’s been sheltering for years.
