Sky to Sky by Amanda G. Stevens

Zac is a longevite. Immortal, and angry. His public persona is a stunt man, who posts videos of his exploits. An internet sensation. What they don't know is that he is tortured, suffering from PTSD, crippled by it. Angry at God for his life. Angry at another longevite who chose to be a serial killer. This is a complex story that draws you in and won't let you go until the very last page. Savor every page. It is worth it.
