A beautifully written and translated collection of poems centered on loss and displacement. While you could read "the lover" invoked throughout as an actual person - and may, in some instances, be referencing someone specific - I feel like the poet means to reference country and culture. The speaker has been forcibly removed from his culture and so mourns it like a lost lover.
Read for 2017 Read Harder challenge. Thanks @JessReads for the rec.
