Warning! Here be huge spoilers! Read the book first!This isn’t a book review. A book review would focus on the merits of the book—perhaps the characterization, a nod to the complicated and convoluted plotting, occasional felicities of language, and so on. Having marathoned my way through George R.R. Martin’s most recent entry in the Song of Ice and Fire, I’m still in the “Wow!” “No way!” “Arrgh!” stages of the reading process.
