A fascinating speculative-fiction story: the time is 2072 and the place: The Einstein Intercontinental Time-Port and associated Paradox Hotel. Yes, there is time travel for tourists, to visit, for example, Ancient Egypt or the Triassic Period. January Cole works for the Time Enforcement Agency providing hotel security and she has an extraordinary caustic and acerbic personality. The story is really about the nature of time, but also grief and memory. And there are murders, dinosaurs and maybe ghosts: a thrilling read.
