This expansive, ambitious collection by Joe Pan further exemplifies his talent for blending genres and pushing formally experimental narratives and lyrics into a wild array of thought-provoking poetry. From the familial to the fantastical to the socially political, Pan's maximalist style doesn't miss much, earning this collection its place among the most anticipated books of 2019. Highlighted by "Ode to the MQ-9 Reaper," a long poem about drone warfare already taught in classrooms around the country--Operating Systems approaches our complicated and shifting histories with empathy and an eye for the absurd.
