Hayden Han is a grieving travel influencer with ten million followers and no one to call. With Christmas looming, he takes on a dodgy brand deal solely on the promise that it will take him far, far away from his lonesome home life--in this case, twenty-four hours on the white sand beaches of the Philippines. But Manila has its own plans for Hayden, and as day turns dusk (tagalog: silim) in the City of Sun, Hayden finds himself pulled into a roiling high-speed chase that brings him face-to-face with the man he's becoming.
