I don't know anything about this answer so I cannot judge whether this works.

'pure tears with novel that's extraordinary' is the wordplay.
'with' says to put letters next to each other.
'that's extraordinary' indicates anagramming the letters.
'pure'+'tears'+'novel'='puretearsnovel'
'puretearsnovel' with letters rearranged gives 'PLEASE TURN OVER'.

'read' acts as a link.
