“The stakes are high, trust is gained or lost, and in many cases, deception proves to be the ultimate weapon. Although On the Precipice is set in a fantasy world, it had me thoroughly glued to the reality of the dynamics of politics. For this novel to succeed, Brianna MacMahon created exceedingly complex characters who, by virtue or vice, roused me with their words and actions. The continuity of each one’s character or nature is steadfast, making for authenticity and a hyper-immersive novel. The dialogue is also intriguing, ranging from meaningful conversations to sarcasm and, at times, hilarious wit. I also enjoyed how there was always an air of suspense leading up to major events and how I never knew what to expect next. This novel towers above many others for its exceedingly skillful craftmanship of characters in a world where the weaker will get by but the strong will thrive.” -Paul Zietsman 
“Brianna MacMahon’s On the Precipice offers readers a story of masterful world-building and intricate character exploration. Set in a universe rife with political intrigue, the story takes us into the personal lives of a huge cast that drives it through shifting perspectives and alternate storylines. Science fiction tends to be a recycling factory that churns out iterations of the same foundational stories, but MacMahon’s social structure, politics, and system are really refreshing. Many of her characters are worthy of their own offshoots, and Raelynn isn’t the only most interesting one, which is a testament to MacMahon’s skill.” -Jamie Michele

MacMahon makes the time investment worth it.” -Asher Syed

“On the Precipice is a unique sci-fi character study that readers won’t want to miss. [. . .] Each character is given an ample amount of page time, providing an in-depth look at their personal and political lives. [. . .] On the Precipice provides such an in-depth analysis of the characters and the political scenes of Imperium that one could easily see parallels with the politics of Earth.

The good, the bad and the flawed — you’ll find them all in this story.” -Katie Bloomer
