Here with Me (Adair Family #1) by Samantha Young (2021, Trade Paperback)

Settled in the tranquil remoteness of the Scottish Highlands, Ardnoch Estate caters to the rich and famous. It is as unattainable and as mysterious as its owner —ex-Hollywood leading man Lachlan Adair—and it's poised on the edge of a dark scandal.After narrowly escaping death, police officer Robyn Penhaligon leaves behind her life in Boston in search of some answers. Starting with Mac Galbraith, the Scottish father who abandoned her to pursue his career in private security. To re-connect with Mac, Robyn will finally meet a man she’s long resented. Lachlan Adair. Hostility instantly brews between Robyn and Lachlan. She thinks the head of the Adair family is high-handed and self-important. And finding closure with Mac is proving more difficult than she ever imagined. Robyn would sooner leave Ardnoch, but when she discovers Mac is embroiled in a threat against the Adairs and the exclusive members of the estate, she finds she’s not yet ready to give up on her father. Determined to ensure Mac’s safety, Robyn investigates the disturbing crimes at Ardnoch, forcing her and Lachlan to spend time together. Soon it becomes clear a searing attraction exists beneath their animosity, and temptation leads them down a perilous path.While they discover they are connected by something far more addictive than passion, Lachlan cannot let go of his grip on a painful past: a past that will destroy his future … if the insidious presence of an enemy lurking in the shadows of Ardnoch doesn’t do the job first.
