Harking from Aotearoa New Zealand, this book provides an account of the  postqualitative  approaches employed to map the worlds of four trans secondary students and the possibilities for gender justice that these worlds offer. Reading these maps through an agential realist lens affords a sense of the material-discursive, multiplicitous, dis/continuous, and more-than-human becoming of these students, their genderings, and the worlds that co-constitute them. These dynamics are a hauntological matter: the im/possibilities of students& presents are never simply here-now, entangled with pasts that have (not) been and futures that will (never) be. This is manifestly evident in the way the colonial invention of gender haunts students& worlds, constraining response-abilities, but also in the wondrous potentialities that lie in wait at the edge of possibility, reminding us that more just worlds are always already present (even if only as exclusions). An agential realist ethics of response-ability requires tracing the entanglements that constitute the ongoing reconfiguration of relations that embody reality, or  spacetimematterings , as a means of renegotiating im/possibilities.
