When teenage super-scientist Joanna "Johnny" Chambers invents a clean energy generator in 2002, it draws the attention of malevolent extradimensional gods.
Now, Johnny and her childhood best friend Nick Prasad must travel the world in a desperate attempt to find and close the Gate before a cosmic alignment allows the forces of evil to return.
[3] James Nicoll lauded Mohamed's depiction of "the vexed relationship between Johnny and Nick", and observed that her portrayal of the Ancient Ones as "highly invested in preventing anyone anywhere from enjoying long-term happiness" made them the equivalent of "inter-dimensional griefers".
[4] At Strange Horizons, S. Qiouyi Lu emphasized that, despite the many positive outcomes of Johnny's inventions, Johnny is still a "villainous mad scientist" who "channel(s) great evil", and commended Mohamed for not romanticizing the codependent nature of Nick's magically-enforced love for Johnny which, Lu felt, made Nick a slave; ultimately, Lu found the novel to be "near-flawless", with a "brilliantly constructed narrative" that also serves as an "extended metaphor" in which "Johnny's covenant, and Nick's role as her 'companion,' are tools to critique the legacy of colonialism".
[5] Lu further explored the novel in an essay at Tor.com, in which they described Johnny as "a symbol for coloniality", and noted that Indo-Guyanese-Canadian Nick's identity as a self-described "brown" man in the medium-term aftermath of 9/11 (even if, in the world of the novel, the attacks on the World Trade Center narrowly failed when both jetliners crashed into the Hudson River) "is not an incidental part of the narrative — it drives the narrative," and shapes not just Nick's internal voice but also "how he reacts and makes decisions".
