Summon artist that's difficult to put down (4-6)

Ross

I believe the answer is:

page-turner

I'm a little stuck... Click here to teach me more about this clue!

'difficult to put down' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'summon artist' is the wordplay.
'summon' becomes 'page' (paging is a kind of summoning).
'artist' becomes 'turner' (19th century british painter).
'page'+'turner'='PAGE-TURNER'

'that's' is the link.

Can you help me to learn more?

(Other definitions for page-turner that I've seen before include "exciting book" , "'Unputdownable' book" , "Book one can't put down" , "Gripping book" .)

I've seen this clue in The Guardian.
