Trying echo'ing out the delete query:
$delete = 'DELETE FROM lounge WHERE isbn = $ROW[\'isbn\']';
echo $delete
And see what you get. You'll probably get exactly what you see above
since PHP variables are not parsed inside single-quoted strings. Try
this instead:
$delete = "DELETE FROM lounge WHERE isbn = {$ROW['isbn']}";
$del_query = $db->($delete);
