Summon artist creating fantastic book (4-6)
I believe the answer is:
page-turner
'fantastic book' is the definition.
'page turner' can be an answer for 'book' (I've seen this before). I am not certain of the 'fantastic' bit.
'summon artist' is the wordplay.
'summon' becomes 'page' (paging is a kind of summoning).
'artist' becomes 'turner' (painter JMW Turner).
'page'+'turner'='PAGE-TURNER'
'creating' is the link.
Can you help me to learn more?
(Other definitions for page-turner that I've seen before include "Book one can't put down" , "exciting book" , "Gripping book" , "'Unputdownable' book" .)
