Format JSON ojects for Ember / drill-down / serialize / adapter

I'm pulling some JSON with ajax (because I can't get past CORS with my limited understanding/lack of useful examples/ of the RESTAdapter...) - and I'm getting these nested objects. I need an array of the 'book' - but I'm unsure of how to format this JSON so that it's readable.

routes/books.js

import Ember from 'ember';
import ajax from 'ic-ajax';

var libraryThingApi = "http://ift.tt/1GbEbod?";

export default Ember.Route.extend({

  model: function() {

    var libraryData = ajax({
      url: libraryThingApi + "userid=F.L.O.W.",
      type: 'GET',
      dataType: 'jsonp'
    });

    console.log(libraryData);
    return libraryData;
  }

});

what is returned

Promise
  _id: 47
  _label: "ic-ajax: unwrap raw ajax response"
  ...
  _result: Object
    books: Object
      111333266: Object
        title: "a book title"
      111730480: Object
        title: "a book title"
    settings: Object
      theuser: "F.L.O.W."
      more_things: "etc"
