Apologies for a very late post on this - I had scheduled it 'way back in June and now can't find the post.
The Little Prince by Antoine de Saint-Exupery
Category: Lost Book Club
The unnamed narrator crashes his plane in the desert and comes across the little prince, an alien boy visiting earth from asteroid B-612, who has a lot to say about a child's faith and matters of "consequence."
This is a rather strange little story, and I'm afraid to say to much about it without giving out spoilers, since it's only 91 pages long. Imagination, faith, and the inability of most grown-ups to see what is truly important are recurring themes. 4 stars.
In all fairness, this may be stretching the "Lost" category. Though there was an episode entitled "The Little Prince," the book doesn't show up on abc.com or on the lostpedia.com list of Literary works, so take from that what you will. :-)
