The First Thousand Trees (ECW Press) by Premee Mohamed is the final novella instalment in the Indo-Caribbean author’s post-apocalyptic series The Annual Migration of Clouds. Deepening the repercussions of climate devastation established in books one and two, The First Thousand Trees follows an unexpected, even unlikely character as its protagonist, tracing his journey in the aftermath of his friend’s departure. Mohamed unwinds notions of failure and the limits of friendship in the novella form, propelling both the individual book and the wider trilogy to a deeply satisfying — though not uncomplex — resolution.
