ezekiel

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

'book' is the definition.
(I've seen this before)

'zwickau's leader into east european city in germany' is the wordplay.
'leader' suggests taking the first letters.
'into' is an insertion indicator.
'east european' becomes 'EE' (abbreviation).
'city in germany' becomes 'kiel' (I can't justify this - if you can you should believe this answer much more).
The first letter of 'zwickau' is 'z'.
'z' going into 'ee' is 'eze'.
'eze'+'kiel'='EZEKIEL'

Can you help me to learn more?

(Other definitions for ezekiel that I've seen before include "Good book" , "Valley-of-bones prophet" , "Biblical prophet" , "Hebrew prophet" , "OT book, prophet, priest" .)
