Another book people may be interested in is
Wilfred Owen's 'Selected Poems'.
I got it earlier this year when NedC started a thread in the Freebies section,
here.
It may still be free.
I've been dipping into it but I'm not great at understanding poetry so whilst I can imagine or relate generally to the material, I do find it a bit incomprehensible. (That just shows my ignorance of course, because Owen's is claimed as one of
the best poets of his generation.)
