Thank you! I've got plenty more in process -- the fourth, The House of the Crows, is at the publisher already and will be out this coming fall, the fifth, The Sign of the Phoenix, is a little over 3/4 done right now -- I worked out a tricky scene this evening; the sixth and seventh, The Greater Key and The Marble Sphinx, are in outline with chunks of prose, and the eighth, which I haven't named yet, is in outline. Nor will that be the last -- Ariel's story is still very much picking up speed, with new story arcs coming into the picture as I go. There's quite a bit still to learn about Theophilus Cray's backstory, for example, and those curious letters from the Heptasophic Order are setting the stage for something interesting...
