Sahle is transported to another realm on the night of her twentieth birthday in order to become Queen. This new world, the Alterealm, is nothing like the suburban life she's led. Everything she knows is suddenly irrelevant, and even the people she thought were her parents are not what they seem.

In this foreign land, Sahle must quickly learn all there is to know about the Alterealm, the magical abilities she supposedly possesses, and her own destiny as a prophesied peacemaker. The problem: she doesn't have any magic, she is woefully unprepared to be Queen, and one particular Lord seems hellbent on destroying her reign before it can even begin.

As family secrets are revealed and threats to her kingdom mount, Sahle struggles to reconcile who she is with the Queen she must become. The fate of a nation depends on it. Set before a backdrop of a reimagined colonial Africa, A Certain Slant of Light is at once a commentary on history's impact on the present day, and a consideration of how free will collides with fate.
