Every young reader is entranced, at first, to see predator's lair (5)
I believe the answer is:
eyrie
'see predator's lair' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'every young reader is entranced at first' is the wordplay.
'at first' indicates taking the first letters.
The first letters of 'every young reader is entranced' is 'EYRIE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for eyrie that I've seen before include "Nest of 19 Across" , "Eagle's lair" , "Eagle nest" , "lofty dwelling" , "Bird of prey's high nest" .)
