The Carousel of Forgotten Places - S. Hati

First rule: Don't mess with the timeline. Second rule: Don't mess around with the time-god. For 500 years, immortal timekeeper Ryka has run a cozy magical fair on the edges of time, managing the time threads and protecting the spirits that live there. She lives happily among a found family of quirky ghosts, a spectral cat, and even her insufferable boss, the annoying (and sexy) time-god Everest. But when the carousel at the heart of the fair begins to show signs of time rot, a live human falls through time and ends up landing at their feet. With the fair descending into chaos, Ryka and Everest must team up to get this human home, find the source of the rot, and keep the fabric of time from tearing apart - all while hoping that the 500 years of feelings between them don't get in their way.
