No need to unbind.
$data = $this->User->find(
'first',
array(
'conditions' => array(
'User.id' => $id
),
'fields' => array('...'),
'contain' => array(
'Book'
)
)
);
That should get you just the Books for this User, and not all the
Users for each Book.

Sure, it'd save having to fetch the extra data, allocate memory, etc.
