I loved the Wordsworth Edition of this book, it has an amazing introduction (and notes) by Owen Knowles. The poems are ordered chronologically so you can see the changes in Wilfred Owen's writings, especially after his enlistment. The fact that he wanted his poems to include and be also understandable by his fellow soldiers make his writing easy to read and emotive. I loved this book, but going through it is a very taxing experience, every stanza is full of sadness and reality. Yes, 'Dulce et Decorum Est' is one of Owen's most known poems, but there are many other with such powerful situations, like the aftermath of war (as expressed on 'Disabled') and shell-shock.
