How can I query between two columns while still taking advantage of indexes?

Question

Imagine I have a table contains all the chapters of a book and the start/end page from each chapter.

chapter |   start_page     | end_page
--------------------------------------
   1    |        1         |    24
   2    |        25        |    67
   3    |        68        |    123
   4    |        124       |    244
   5    |        245       |    323

I'm attempting to find out what chapter a random page falls on, let's say page 215 for example.

My first idea was to use a query like this

SELECT `chapter`
FROM `book`
WHERE `start_page` <= 215
AND `end_page` >= 215

Unfortunately MySQL can not take advantage of indexes in the above query which is a large problem due to the large size of my table.

After doing some research I came up with this query which does take advantage of indexes.

SELECT `chapter`
FROM `book`
WHERE `start_page` <= 215
ORDER BY `start_page` DESC     
LIMIT 1

The issue now is I want the ability to query multiple random pages while still taking advantage of indexes. It doesn't seem likely that I can modify my last query since it's so heavily reliant on limiting results to one.

Any advice would be much appreciated!

UPDATE: Thanks to a comment from Ray Toal I have a query which gives me the results I need with amazing performance.

SELECT chapter 
FROM book 
WHERE (start_page = (SELECT max(start_page) FROM book WHERE start_page <= 73) AND end_page >= 73) 
OR (start_page = (SELECT max(start_page) FROM book WHERE start_page <= 92) AND end_page >= 92) 
OR (start_page = (SELECT max(start_page) FROM book WHERE start_page <= 300) AND end_page >= 300)

Answer 1

Isn't it as simple as this?

select max(chapter)
from book
where start_page <= 215;

If end pages follow previous start pages, this will work.
