basic problem with child theme

I have just moved my blog from wordpress.com to wordpress.org. The new site is http://colourware.org/

I have used the twentythirteen style and everything looks pretty good. However, I wanted to modify one page because I have an amazon astore that doesn’t quite fit with the sidebar on the right. So I need to make a page that is wider.

I decided to use a child theme. I created a directory called twentythirteen-child in my themes directory and in that director I put a single file called style.css. The contents of that file were


/*
Theme Name: Twenty Thirteen Child
Theme URI: http://example.com/twenty-thirteen-child/
Description: Twenty Thirteen Child Theme
Author: John Doe
Author URI: http://example.com
Template: twentythirteen
Version: 1.0.0
*/


@import url(“../twentythirteen/style.css”);

Now what I would like to do is add a file called page-bookstore.php

However, before I changed anything I activated the childtheme to check everything was working. When I activate it it works but two menu items disappear including Home. When I activate the parent theme again the menu items come back.

Now I could start adding these menu items back in again and correcting any other quirks. But it seems wrong. It seems to me that I am doing something wrong because my child theme inherents the style of the parent theme and everything should stay the same. Right? Or have I got that wrong?

Many thanks for any comments
