I don't really like Bean. In Ender's Shadow, he seemed like some kind of freaky Marty Stu that Card changed so that he could continue the series. I don't think Card loves Ender the same way he loves Bean, which is why Ender, despite being the most brilliant doesn't come off as a Stu.
The books are freaking addictive now though. Does Peter show up for any significant amount of time in Shadow Puppets? I know Petra has Bean's babies or something, but I don't Peter's involvement.
