This queer, modern retelling of Hamlet is set in a scientific lab and contained mostly within a tense 12 hours. Hayden Lichfield finds his father's cooling body in Elsinore labs within the first few pages; he immediately calls on the sentient AI system, Horatio, who controls the security cameras and many other aspects of the building. Horatio reports a 1.5 hour gap in the video logs. Hayden and his father, Dr Lichfield, were working on formula to reverse death. Hayden's immediate assumption is that the killer was after his father's research. The lab goes into lockdown and Hayden is trapped inside with his uncle Charles, lab technician Gabriel Rasmussen, Hayden's ex and research intern Felicia Xia, and her father Paul Xia, head of security. Unless they find an intruder, one of them is the murderer. I enjoyed how deftly this novel kept me guessing even when following a plot I know well. I was genuinely unsure how many, or who, of the people trapped in Elsinore would survive the night. I was also into the unashamed queerness of an AI in love with a human, and the ways in which that love could and could not be reciprocated.
