Hard Limits

She wasn't supposed to see him. He wasn't supposed to let her live.
Wildlife photographer Reeve Callahan has spent ten years disappearing into the Sierra backcountry, her lens the only witness to landscapes most people never see. Tracking a mountain lion through the snowfields above Lake Tahoe, she captures a single frame she wasn't meant to capture - a man on a ridge who shouldn't exist, photographed from a
distance he never should have allowed.
He finds her before the memory card cools.
Creed is everything the wilderness produces when the wilderness stops being the point. Former intelligence operative. Currently off-grid. Running an operation against an organization called Vane that has killed for less than what's on her camera. He has two choices: deliver her to the people hunting her, or keep her alive long enough to finish what he started.
He chooses the second.
What begins as forced protection - a reinforced cabin, a storm she can't outrun, a partnership neither of them asked for - becomes something harder to name. Four days in a blizzard. A twenty-mile evacuation through terrain that would kill them both if they stopped trusting each other. The slow, dangerous discovery that the most precise attention either of them has ever received is the attention of the person who should be their enemy.
When they reach Sacramento, the war isn't over. Vane's reach extends further than Creed knew. Adrienne Voss - a lawyer who has been waiting years for the right evidence - needs Reeve to testify. Creed needs her to survive the testimony. And Reeve needs to decide whether what she built in a storm can survive the ordinary daylight of a life neither of them has lived yet.
Hard Limits is Book One of the Ridge Runners, a trilogy about two people building something real on ground that keeps shifting underneath them. For readers of Emily Henry's emotional precision, the slow-burn intensity of Ruth Ware, and the atmospheric romance-thriller register of Lucy Foley. If you love a heroine whose competence is the whole point, a hero whose stillness is more terrifying than his training, and a romance that earns every inch of its heat - this series is your next obsession.
