Queries :: Max Not Showing Only Biggest Date

I have 3 Tables with relationships between Pupils to Read and Books to Read:

Pupils ID, Forename, Surname
Books - BookID, Book, Author, Level, Genre
Read - ID, BookID, DateOut

On another thread in the forum I got to the position of the code below. However this code does not select only the read book with the biggest(latest) date, the Max, it displays all Read books.

SELECT Pupils.ID, Max (Read.DateOUT) AS MaxOfDateOut Books.Book
FROM (Books) RIGHT JOIN (Read) ON Books.BookID = Read.BookID) RIGHT JOIN Pupils ON Read.ID = Pupils.Id
GROUP BY Pupils.Id, Books.Book
HAVING (((Books.Book)<>"Blank"));
