One ex-marine. One woman looking for her brother. One ancient lost city in the Andean rainforest.

Former Marine Logan O'Connor is big, rough and a little wild. He served successfully in the navy...but one day he trusted the wrong woman. After a horrific betrayal nearly kills him, he works for his best friend at Treasure Hunter Security. Logan doesn't like sand, jungles, or mosquitoes, but he still does his job - ensuring the safety of archaeological excavations and expeditions. However, he dislikes liars even more. Going to Peru with a cold, elegant corporate boss looking for her brother, Logan knows for sure: Sydney Granger did not tell him the whole truth.

After the death of her father, Sydney Granger tries to get used to the position of CEO of the enterprise, while her brother runs away to study Inca culture. But soon a ransom call horrifies her - her brother has been kidnapped by a deadly black market in antiquities. Now Sydney can only rely on the "Treasure Hunter Security Service", including the big annoying Logan, who doesn't even hide his antipathy.

When Logan and Sydney go into the Andean rainforest on the trail of the mysterious cloud warriors, danger lurks at every step. They are getting closer to each other, secrets are revealed, bullets are whistling around, and that’s when the chance to find something more valuable than treasure appears.
