Past Due: A Collection Of Poems, Byron Lee

Theses

"Past Due" is a co1lection of poems written almost entirely in free verse and almost exclusively based on personal experience. I find, at least at this point in my growth as a writer, that when I try to adhere to poetic structure, I feel confined. My style is sparse because I feel that this aesthetic best cuts to the emotion I'm trying to convey. I also love playing with line breaks, since I find that doing so can give several lines in a poem their own statement, like each poem makes its own statement even when bound in a co1Iection …
