Are there any good Comp Sci A books that aren't Barron's?

<p>I was looking around and the latest version I could find of the Princeton Review was 2006-2007. Are there any good books specifically geared towards the Comp Sci A exam? I intend to finish two workbooks so I have more than one explanation for the concepts so I understand it better.</p>
