Laravel eloquent relationship chaining

I have three table shares, share_users, users structure as follows -

users ( Table ) -
     -id
     -name
     -email

shares( Table ) -
     -id
     -name

share_users - 
     -id
     -user_id
     -share_id

I want to retrieve user data from share model using Laravel eloquent relations.

Thanks in advance.
