Parsing JSONArray in apex

i am trying to parse a response which is a json object in this json object there is a token with name items and whose value is a json array how to parse this json array

 

my json object is 

 

{
 "kind": "calendar#calendarList",
 "etag": "\"ZrhdJMCgpoUK_a5fT7XOC6xn46g/plXZGPvcPHrJh8umego5vRMYLrw\"",
 "items": [
  {
   "kind": "calendar#calendarListEntry",
   "etag": "\"ZrhdJMCgpoUK_a5fT7XOC6xn46g/_sj3j6dReaKvgLTRpRDkSz1mIAU\"",
   "id": "#contacts@group.v.calendar.google.com",
   "summary": "Contacts' birthdays and events",
   "description": "Your contacts' birthdays and anniversaries",
   "timeZone": "Asia/Calcutta",
   "colorId": "12",
   "backgroundColor": "#fad165",
   "foregroundColor": "#000000",
   "selected": true,
   "accessRole": "reader"
  },
  {
   "kind": "calendar#calendarListEntry",
   "etag": "\"ZrhdJMCgpoUK_a5fT7XOC6xn46g/wnz2e6fAz2dY8LnmrEb74dwcspc\"",
   "id": "en.indian#holiday@group.v.calendar.google.com",
   "summary": "Indian Holidays",
   "description": "Indian Holidays",
   "timeZone": "Asia/Calcutta",
   "colorId": "15",
   "backgroundColor": "#9fc6e7",
   "foregroundColor": "#000000",
   "selected": true,
   "accessRole": "reader"
  },
  {
   "kind": "calendar#calendarListEntry",
   "etag": "\"ZrhdJMCgpoUK_a5fT7XOC6xn46g/hlANK5jBgx_YHUEAnXhn6WANZ4A\"",
   "id": "ritesh@iritesh.com",
   "summary": "ritesh@iritesh.com",
   "timeZone": "Asia/Calcutta",
   "colorId": "9",
   "backgroundColor": "#7bd148",
   "foregroundColor": "#000000",
   "accessRole": "owner",
   "defaultReminders": [
    {
     "method": "popup",
     "minutes": 10
    }
   ]
  }
 ]
}

 

now for parsing i am using code

   Map<String, Object> m = 
   (Map<String, Object>)
      JSON.deserializeUntyped(re); //re is response body string
List<Object> a = 
   (List<Object>)m.get('items');
   System.debug(String.valueOf(a.get(0)));
   Map<String, Object> m1 = 
   (Map<String, Object>)
      JSON.deserializeUntyped(String.valueOf(a.get(0)));
 System.debug('Summary is'+m1.get('summary'));

 

  System.debug(String.valueOf(a.get(0))); returning

{accessRole=reader, backgroundColor=#fad165, colorId=12, description=Your contacts' birthdays and anniversaries, etag="ZrhdJMCgpoUK_a5fT7XOC6xn46g/_sj3j6dReaKvgLTRpRDkSz1mIAU", foregroundColor=#000000, id=#contacts@group.v.calendar.google.com, kind=calendar#calendarListEntry, selected=true, summary=Contacts' birthdays and events, ...}

when i run this code i am getting error  

FATAL_ERROR|System.JSONException: Unexpected character ('a' (code 97)): was expecting double-quote to start field name at [line:1, column:3]

  because accessrole is ot surrounding with double quotes i am getting this error can any one please help how to get summary field from json array please provide a suitable method for parsing the response??

List<Object> lstObject = (List<Object>)m.get('items');
for(Object result :lstObject) {
  Map<String,Object> mpParsed = (Map<String,Object>)result;
}

 

The object returned by parser is to type Map<String,Object>, hence it needs to be typecasted before using further in the code
