**Undoing traditional psychiatric narratives in this innovative and bold first collection. ** Drawing from queer, trans, disabled, and Mad poetic traditions, Differential Diagnosis introduces a deeply entangled transMad approach, investigating ways of knowing, loving, and living not legible to the normative eye. This collection challenges the architecture of institutional psychiatry and its popular “wellness” analogues, offering instead a counternarrative of forced institutionalization, disorderly embodiment, and transMad self-determination. At once jarring and joyful, Differential Diagnosis interrogates psychiatric power and locates capacities for disabled and/or transMad resistance in the oblique, the speculative, and the “nonsensical. ” Cavar’s inventive full-length debut defamiliarizes cis, sane, abled existence through linguistic play and speculative imagery, offering Madness not only as poetic content, but also as craft technique and, ultimately, as a new way of being in the normative world.
