As head of security at the Paradox Hotel, January Cole has several problems. The ultra-wealthy guests arriving for their time travelling tours are stuck in the hotel due to an unexpected storm, and there seems to be a corpse only January can see in room 526. Furthermore, a couple of trillionaires are visiting the hotel because the US government has decided to privatize time travel. January is certain the timing and the trouble seemingly brewing inside the Paradox Hotel aren't just a coincidence. Now, she must do everything possible to catch an invisible killer as January's past, present, and future collide.

The Paradox Hotel is an exciting read, almost like when sci-fi meets mystery/thriller, except the science isn't clearly explained, the mysteries are manifold to the extent of confusion, and the thriller fails to convey the urgency. I was disoriented with the different puzzles, and tracking what issues needed to be solved was difficult while reading. The character development chapters also make the flow somewhat choppy and aren't that interesting to read. I wish Rob Hart could have just focused on January solving the mysteries and making The Paradox Hotel much faster-paced.
