Savage Secrets by Em Petrova

This tormented hero has always been misunderstood…until he meets her.

Zach Webb is loyal to the ranch he manages. He’s also accused of wrongdoing and misunderstood. Overcoming the rumors about his role in thefts and crimes against the Gracey family has him determined to stay. Only now he’s sent to protect a neighboring ranch that’s also under attack…and that protection extends to the woman who owns it. Guarding Opal comes easy—but keeping his hands off her is one of the biggest challenges he’s ever faced.
Following her father’s death, hardened single mother Opal Vale is determined to keep his legacy alive. Trouble is, saving the Springvale Ranch is proving to be much more difficult than she thought. When Zach, the growly ranch manager, barges into her life and takes over, she doesn’t know whether to convince the grumpy cowboy that she doesn’t need him—or let the man take over with his smoldering kisses.
Keeping the ranch out of the hands of a ruthless investor is Zach’s goal. Falling for the woman he’s vowed to protect isn’t…and Opal’s battle to keep the ranch might be easier than risking her jaded heart.
