Nothing but Air by Olivia Stream

A forgotten inheritance. A hidden fortune. A dangerous climb that could uncover the truth or bury it forever. After her grandmother’s death, structural engineer and former climber Avery Shaw returns to the isolated island of Whistler’s Crown. Waiting for her is an old brass key, a trail of coded clues, and the legend of a treasure lost more than a century ago. But when someone breaks into her family home and sabotages her climbing rope, Avery realizes the treasure is more than an island story. Rescue captain Jonah Reed has spent nine years carrying the guilt of the climbing accident that killed Avery’s brother. He never expected Avery to return, and he certainly never expected to follow her back onto the cliffs that shattered both their lives. Yet protecting her means confronting the past, including feelings for her that never truly disappeared. Their search leads through flooded caves, abandoned lighthouses, forgotten tunnels, and the deadly heights of Saint’s Needle. With every clue they uncover, the danger grows. Someone is willing to burn records, destroy evidence, and kill to keep the island’s darkest secrets hidden. What Avery and Jonah discover could expose a powerful family, restore stolen land, and reveal the truth about her brother’s death. But surviving the final climb will require more than courage. Avery must decide whether she can trust Jonah again, face the faith she abandoned, and believe that healing is possible even after devastating loss. Above the sea, there is nowhere left to hide. Noth­ing But Air is an emotional Christian romantic suspense novel filled with forbidden secrets, dangerous climbing, buried treasure, second-chance love, faith, betrayal, and the courage to begin again.
