Fans of the Kingdom Keepers series who are sad after finishing the final installment this spring won't have a longer-than-usual wait to be reunited with some of their favorite literary characters. That's because author Ridley Pearson announced on his website and social media this week that he is working on a trilogy that picks up where book seven, "The Insider," left off. And, true to the pattern of the last several years, the first follow-up novel will be released next spring. "The Return: Disney Lands" has a publication date of March 31, 2015.
