Moxie's Decision has a picked up quite a few good reviews. Here's a typical one:
Moxie’s Decision by Hank Quense introduces readers to a world of Camelot worthy of a Monty Python parody. Moxie is a frustrated princess who has a head for business and big plans for her father’s cash-strapped kingdom. There’s only one problem with her plan, though. Her father, King Smedley, refuses to acknowledge her as his heir and her hateful Uncle Orrin has plans to eliminate Moxie in order to have his young son become ruler of Usca with him calling the shots as regent. This would be paralyzing for most young princesses of her ilk but Moxie isn’t like most princesses. She’s got brains, determination – and most important of all, moxie. She puts her plans into action by enlisting the help of three of Lancelot’s knights, Percivale, Bors and Gareth. She talks them into taking her to the Heroes Guild with plans to have them endorse her so that she can be trained in the art of fighting – a most important endeavor if Moxie plans on holding her own – and staying alive.
