Doctor Who meets Only Murders in the Building in this propulsive speculative young adult thriller following an apprentice time traveler who finds a dead body in her bathtub and races to solve the murder…before it happens.

Welcome to the Nexus: the only hotel in Toronto to cater to the modern time traveler. With temporal security in place for your protection, color-coded tokens to keep paradoxes at bay, and housekeeping on linear Tuesdays, the hotel is ready to serve all your needs.

Agatha Grey is a long-term resident at the Nexus. As an apprentice time traveler, Agatha is mostly limited to sourcing ancient grains for fad diets. Her work is pretty boring, but she likes it that way, as she’d rather escape into the past than actually deal with her grief over an accident that left her the only survivor.

But when Thomas Charger, a (sort of) friend, turns up (definitely) murdered in her hotel bathtub, Agatha can no longer keep her life on pause. If she wants to know who killed Thomas—and why they chose her bathtub to do it in—she will have to venture deeper into the mysterious Nexus Hotel and attempt to learn its secrets, which becomes all the more complicated when Thomas shows up in the middle of her investigation.

In a hotel for time travelers, time means nothing. So how do you solve a murder that hasn’t happened yet?
