The GtkAda folks have released a new version of GtkAda for Gtk+-2.2 and it includes an easily installed binary release. It looks to me like the easiest way to get started writing cross-platform Gtk+ programs is to install GNAT 3.15p and GNATWIN then install the new GtkAda release. Reasonably complete examples are included in the distribution.
The Other Wind and Tales from Earthsea, by Ursula K. LeGuin. I was very glad to see that there were still Earthsea tales that LeGuin wanted to tell. Both of these books are quite good.
A College of Magics by Caroline Stevermer. This is a very entertaining Ruritanian fantasy in an alternate world with a touch of magic. I've enjoyed her other works as well: The Serpent's Egg, When the King Comes Home, and Sorcery and Cecelia (co-written with Patricia C. Wrede). I haven't read River Rats yet, though.
The Haunted Monastery, a Chinese Detective Story, by Robert van Gulik. An enjoyable Judge Dee mystery.
