How to create a menu for current book
I was surprised that I couldn't find a contrib module that does this out of the box so I created a simple one.

Here it is on Github too:
https://github.com/balsama/bookoblock (bookoblock = "Book Outline Block")

Info file (bookoblock.info):

name = Book Outline Block
description = "Provides a block containing an outline of the current book."
package = Other 
core = 7.x
dependencies[] = book


Module File (bookoblock.module):

&lt;?php
/**
 * Define the Book Outline Block/
 * Implementation of hook_block_info()
 */
function bookoblock_block_info() {
  $block['book_outline'] = array (
    'info' =&gt; 'Book Outline',
    'cache' =&gt; DRUPAL_CACHE_PER_PAGE,
  );  
  return $block;
}

/**
 * Define the contents and title of the block/
 * Implementation of hook_block_view()
 *
 * Returns a renderable block array containing the current book's outline if
 * the node is part of a book.
 *
 * Returns NULL if the current menu item is not part of a book heirarchy.
 */
function bookoblock_block_view() {
  if ($book = bookoblock_is_book_node()) {
    $tree = menu_tree_all_data(book_menu_name($book['bid']));

    // If we pass 1 as the second param, we just get the top level node in the
    // book. Since the key will be the top level mlid, we'll have to use 
    // ['p1'] in the $book array (which contains the top mlid) when we use it 
    // for the block title.
    $book_name = (book_toc($book['bid'], 1));

    // Build the block title and contents
    $block['subject'] = $book_name[$book['p1']];
    $block['content'] = menu_tree_output($tree);

    // Return the block
    return $block;
  }
  // If the current node isn't part of a book, just return nothing.
  return NULL;
}

/**
 * Checks to see if current node is part of a book.
 * Returns book array if it is part of a book, FALSE is not.
 */
function bookoblock_is_book_node() {
  if ((arg(0) == 'node') &amp;&amp; (is_numeric(arg(1)))) {
    $node = menu_get_object();
    if (isset($node-&gt;book)) {
      return $node-&gt;book;
    }
  }
  return FALSE;
}


Just drop those two files into a folder named bookoblock inside your modules directory and enable the module. You'll now see a new block in the block admin page named Book Outline. That block will only appear on node pages where the node is part of a book. It contains a heierarchical menu of the entire book and it's title is the root node's title.
