Mine to Keep by Davidson King

Matt lives a pretty simple life. A physical therapist, he helps people to heal and become their best selves once again. When he’s offered a live-in position at the Saint residence, he accepts easily and for a while, things go smoothly. But then there’s a drunken night…and a possible stalker. Matt is really starting to miss that simple life.
Nick likes computers more than people…except maybe his twin brother. Matt living with them for months on end doesn’t affect him much…until one weird night. Now Nick sees Matt in a different light, and when someone else starts looking at Matt in a very dangerous way, he is filled with a need to help. But will Matt let him? And who is stalking Matt?
When the situation begins to escalate and it appears that Matt’s life may be on the line, Nick refuses to stand on the sidelines—he calls for his family to step in and help. As Nick and Matt get closer in every way, so does the threat. Can Nick and Matt keep one step ahead of danger, or is luck not on their side?
