Go crazy as I read, gripping pages (9)
I believe the answer is:
disappear
'go' is the definition.
(I know that go is a more specific form of disappear)
'crazy as i read gripping pages' is the wordplay.
'crazy' is an anagram indicator.
'gripping' is an insertion indicator (inserted letters are gripped).
'pages' becomes 'pp' (abbreviation for multiple pages).
'as'+'i'+'read'='asiread'
'asiread' with letters rearranged gives 'disaear'.
'disaear' enclosing 'pp' is 'DISAPPEAR'.
(Other definitions for disappear that I've seen before include "Vanish from view" , "Fade out" , "go by the board" , "exit" , "Vanish, cease to be visible" .)
