City dear to Jane Eyre's heart (9)
I believe the answer is:
rochester
'city' is the definition.
(town in Kent)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for rochester that I've seen before include "Jane blindly married him" , "Kent town" , "Medway cathedral city" , "Kentish Town" , "Dickens's favourite city - hero of 12" .)
