The Guardian

You think Santa Claus can't go around the world every year in just one night? Akira has to go around the Prime Meridian once each night. Seventeen-year-old Akira Osei lives in the quiet town of Tema, Ghana, but his life is anything but ordinary. As the latest in a long line of Osei women, he bears the impossible duty of guarding the boundary between the human and the fae worlds. Every single night, Akira walks the entire Prime Meridian, sealing the Isekai- the invisible divide that keeps the two realms apart with the song of the Isekai and the staff of Saikyo Maho. The next night, he does the same in the fae world. Each journey takes exactly three hours, no more, no less. No one- not even his ancestors- knows how or why this is possible. It simply must be done.
But Akira's world is shifting in more ways than one. He's supposed to be the next matriarch, but he doesn't feel like a girl at all- a feeling his strict mother, Kekeli, can never discover. Isolated from school and the outside world, Akira finds unexpected friendship in a group of humans his age, and maybe something more in Amari, a human boy who makes him feel seen for the first time.
Meanwhile, deep in the fae realm, a darker power awakens. Bonsam, the dying Dark Fae King, has learned of Akira's struggles and plans to use him to shatter the boundary between worlds once and for all.
As the veil weakens and truth collides with destiny, Akira must decide who he is and what he's willing to risk before both worlds fall into chaos.
