A wounded veteran who lost his purpose when he lost his legs in battle, and a single mother who only sees the hero he's become. He's lost his purpose... Callum McKay, was an SAS officer when a car bomb took his legs. After his recovery, he became partner in an international security firm - one that dealt with the things governments weren't able, or willing, to deal with. As far as Callum is concerned, he's still the same able, competent and commanding guy he was before his accident. And then, he was proven wrong. After a screwed up mission in South America, Callum realized he was no longer an asset to his team. He was a liability. With his purpose and faith in his abilities shattered, Callum turned his back on the security company and returned to the house his grandfather left him in Arness, Scotland. He was no longer fit for action. He was no longer fit for life. He was no use to anyone at all. ...she's giving it back...whether he wants it or not! Single mother, Isobel Sinclair, has made a lot of stupid decisions in her life. But the dumbest one has to be removing a dead body from the beach outside of her house. She panicked when she saw the dead man and was too scared to call the police, in case they found out her secrets and threw her in jail. Who would look after her kids if she was gone? No, there was no calling the police. That's why the body ended up in her freezer and she ended going to the most terrifying man in Arness to ask for help. Callum McKay was obviously hiding from the world and clearly didn't want to get involved with anyone or anything. Unfortunately for him, he wasn't going to get a choice in the matter - because only Callum could help Isobel now.
