Read my novel with one's head in the clouds (6)
I believe the answer is:
dreamy
'with one's head in the clouds' is the definition.
(I've seen this in another clue)
'read my novel' is the wordplay.
'novel' indicates anagramming the letters (letters in a new or novel order).
'read'+'my'='readmy'
'readmy' is an anagram of 'DREAMY'.
(Other definitions for dreamy that I've seen before include "quite impractical" , "delightful" , "Pleasantly unreal, very attractive (colloq.)" , "Descriptive of the music of a nocturne" , "Lovely" .)
