After the devastating events in the Scottish Highlands, Sam and Declan have moved on to a new, deeper level in their romance. Their commitment to each other is unquestionable; however, there are plenty of questions that need answering about other aspects of their lives, and those who sought to end them.
Sam is trying his best to deal with the day to day frustrations of his injuries. He's completely dependent on Declan for everything and hates the way the scales have tipped in their relationship. Although he's officially on leave, Sam's mind cannot stop replaying all that happened to him and questioning why, and who is behind it all.
Declan's relief at having Sam home throws him into house-husband mode. He's happy to take the reins and care for his partner, however, beneath the surface, Declan cannot help but be drawn back to how he felt in the Highlands, and how they were betrayed by a man who was supposed to have their back. Declan had promised Sir James Aiken that he would pay if he hurt Sam, and now Declan has to decide how he can deliver his payback and put his and Sam's world back on an even keel.
