The Rest of Forever by Jerry Cole

Eric hates going to his parents’ home. Specifically when his abusive father is there to make him feel unwanted. What he doesn’t expect when he walks into his father’s house is to find both his parents, his brother and his sister dead in what appears to be a home invasion. The sole survivor is his brother’s girlfriend.

The only person he can count on is his high school friend Kyron, who happens to be his former crush. Eric is struggling to come to terms with the fact that he might be next victim, and Kyron’s presence is more arousing than comforting.

Kyron is shocked to learn Eric’s family has been murdered. Even more concerning is that Eric could be the next target. As an FBI agent, it’s Kyron’s job to find the killer, but all Kyron is worried about is protecting Eric.

The unresolved sexual tension between them is still there. Kyron is ready to throw his job out the window so he can keep Eric alive—preferably at his side for longer than just this case.
