Here's a sixth Christmas book suggestion: Melissa Lee-Houghton's Beautiful Girls (Penned in the Margins, 2013).
I first read this book at a time when I was not reading much poetry (the only time in my adult life that that was the case), and it re-invigorated my reading of poetry, and I read it multiple times.
(If I humbly mention that there's also my book of poems, I hasten to add that when I "listen" to Melissa Lee-Houghton, I am in the state that I imagine Thomas Hardy could have been with respect to Louis Armstrong – the state of sheer astonishment.)
