Halfway through Xenocide I tossed it aside and vowed never to read another Card novel. The less said about that book the better.That's right about where I quit too. I could only stay interested in philote twining and the Gangean experiments for just so long. I had many friends who told me Xonocide sucked, but I just had to find out for myself - they were right.
If you liked the character of Bean, then you might find Ender's Shadow interesting. It's a retelling of Ender's Game from Bean's point of view. I thought it was a bit too long, and in some ways, it cheapened the original by elevating Bean a little too much. That said, it didn't actually contradict anything in that book.
I'd also recommend the original short story, which I liked better than the book, with all its added on politics and such.
