Peak And Plunder. Whiteout Sins, #34

"I told him he could have anything on the mountain. He said he already did. I didn't realize he meant me."Geologist Marlowe Tate ventures into the unforgiving wilderness of the Yukon Territory with a forged permit and her dead father's journal. She is searching for a legendary, hidden mineral deposit sealed deep inside an unstable, abandoned mine shaft. But Cole Mountain is fiercely guarded by Brecken Cole, an ex-military recluse who will do whatever it takes to protect his family's land from intruders and aggressive corporate mining interests.
When a lethal, multi-day blizzard suddenly strikes, Brecken deliberately sabotages Marlowe's equipment and forces her to take shelter in his remote, snow-buried cabin. Trapped together in a high-stakes, claustrophobic standoff, the fierce geologist and her ruthless captor uncover a decades-old alliance between their fathers. As the storm rages outside, the icy hostility between them melts into a dark, inescapable, and all-consuming obsession.
But they aren't alone on the mountain. Corporate mercenaries arrive by helicopter, ready to use lethal force to seize the land's secrets. Marlowe and Brecken must navigate a dangerous game of survival, descending into the dark, glittering quartz caverns beneath the ice to protect a secret worth killing for.
