Once a samurai, always a Shiver... Kofi Olabasu needs a vacation. He's spent so much time looking out for his brother and working that he's completely neglected himself. To make matters worse, feelings for a man are driving him crazy. The moment Kofi feels Osaki, he knows something is about to change. Confused about his attraction to Osaki, he agrees to take a vacation and accepts Osaki's offer of being Kofi's tour guide in Japan. However, nothing is as it seems. Soon every dark corner is filled with danger and those who wish to do him harm. Osaki has a lot on his plate and love is the last thing he has time for. Not only does he have to get used to his new powers as a Shiver and all the training it involves, but he also finds himself being drawn to a human-though Kofi makes it clear he's into women-and Osaki must respect the man's wishes. All Osaki really has to do is focus on training and being the best tour guide possible for Kofi. But nothing ever goes as planned and soon rogue Shivers are popping out of the woodwork, hell-bent on destroying Osaki for his inheritance. It soon becomes quite clear that they want him dead, and they're not afraid to use Kofi as leverage-or as collateral damage.
