The cover for Tlotlo Tsamaase’s sophomore novel, House of Margins, is here, and Erewhon Books has set a publication date of 26 May 2026.

The book follows Anaya Sebeya, a young writer invited to a prestigious residency at Günter Huis, an eerie colonial mansion on the slopes of Devil’s Peak, where she and four other emerging writers are competing for a grand prize. Anaya never makes it home. What’s left is a true crime podcast, a furious sister named Ranewa piecing together what really happened, and a house that apparently has a great deal more to say. The novel weaves between Ranewa on the outside and Anaya inside the mansion, where time is slipping, visions are multiplying, and the building is demanding something no one is prepared to give.

Tsamaase’s debut, Womb City, established her as one of the most inventive speculative voices to emerge from the African continent in recent years, a Nebula and Locus Award-nominated writer whose work sits at the intersection of Afrofuturism, body horror, and sharp feminist critique. House of Margins pushes further into gothic territory, using the architecture of the haunted house to interrogate colonialism’s cultural legacy and what it costs Black writers to create in spaces that were never built for them.

House of Margins is available for preorder here.
