Review of "Epistle: Leaving" by Kerrin McCadden

Epistle: Leaving by Kerrin McCadden was offered by Poets.org's Poem-A-Day on June 21, 2013.  The poet reveals in her notes that, as she wrote the poem, she thinking about "synecdoche and mathematics."  Ooh, now there's a five dollar word.  "Synecdoche," for those of us who don't know (I had to look it up) is the literary device where a part is meant to represent the whole or vice versa.  For example, "I just received a Dear John," where "Dear John" represents a certain type of epistle.  (At least I knew the meaning of "epistle").
