Ravi Abhiramnew's job is simple: hunt down and neutralize supernatural threats. That is until he meets Cayenne, a charismatic time traveler who claims to know everything about him-even his most closely guarded secrets. Going to dinner with Cayenne is probably a bad idea, and a romantic island getaway definitely is. When a monster picks their resort as its hunting ground, Ravi's combat skills and Cayenne's time magic should make it a breeze to kill the monster and get their vacation back on track.
But it turns out the real danger lurks much, much closer.
