Although Card is a great storyteller, the unfortunate reality is that he's got a very cool idea of an alternative America but he spends all his time in the courtroom. Two books, Journeyman and Heartfire, have Alvin "volunteering" to sit in the courtroom while people argue weighty issues.
I'm listening to the books for free from a wonderful service called Overdrive.com. If you have a library card, then it is likely that you can download free audiobooks. For those of you without a library card or with a penchant for older, scholarly texts, check out the Gutenberg Project. The readers volunteer to read uncopyrighted older texts online for all of us.
