New Novel about Almanzo Wilder?

Amazon.ca has added a listing for an untitled Almanzo Wilder novel to be written by Heather Williams and published in August 2011. Heather Williams, the pen name of Tui Sutherland, is the author of Nellie Oleson Meets Laura Ingalls (2007). Does this suggest there will be more Little House books in the years to come? Stay tuned!
