She puts us back right on the map (3)
I believe the answer is:
sue
'she' is the definition.
'us back right on the map' is the wordplay.
'back' shows that the letters should be reversed in order.
'right on the map' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'us' back-to-front is 'su'.
'su'+'e'='SUE'
'puts' is the link.
Can you help me to learn more?
(Other definitions for sue that I've seen before include "Begin legal proceedings against" , "Bring a legal action" , "Start proceedings against (someone)" , "Take a casa against (3)" , "Litigate" .)
