I’m excited to share that Adverse Events will be published by Spectrum Books, a UK-based publisher committed to LGBTQ+ visibility and community. Spectrum is known for championing bold, character-driven stories and for building a global readership for queer fiction across genres.
Adverse Events is a queer medical thriller set in a near-future United States shaped by dismantled healthcare oversight and institutional failure. The novel will be released in late summer/early fall and distributed worldwide.
I’m proud to be joining Spectrum’s roster of authors and to be working with a publisher whose commitment to visibility, care, and community support is central to its mission. Spectrum’s dedication to championing queer stories—and to materially supporting LGBTQ+ charities—reflects the values that drew me to this partnership. I look forward to sharing more about the novel, the series, and the publication journey in the months ahead.
