Austin "You" Grossman and Robin "Mr Penumbra" Sloan reading, San Francisco, May 11

The next SF-in-SF free science fiction event looks like a seriously fabulous evening: both Austin Grossman (author of YOU) and Robin Sloan (Mr. Penumbra's 24-Hour Bookstore) will give a free reading and then take part in a discussion with host Terry Bisson. It's on Sat May 11, and free (though donations to Variety Children's Charity are solicited).
