Yesterday Percy Jackson author, Rick Riordan, posted a complete transcript of a recent Question & Answer session he held on Twitter (@camphalfblood). The transcript includes answers about upcoming tours, the future Norse trilogy, and teasers for Mark of Athena (out October 2, 2012). You can read the full transcript on the author’s blog at rickriordan.blogspot.com. Riordan also posted photos of the international covers for several of his novels which can be seen below and in our galleries! Which cover is your favorite?
