Fit To Be Tied, written for me, crack cross over in which, courtesy of Anansi the spider trickster, Susan romps through various fictional places dealing with a spider with a sense of humor,
The Rule of Threes Raid, also written for me, Susan is inserted into North Africa to mislead the Nazis about the upcoming invasion of the "soft underbelly of Europe" (a crossover with Rat Patron, which you don’t need to know at all), canon Narnia and my own The Stone Gryphon series
The Case of the Descending Debutante, Lucy, Edmund and Eustace, still with Harold and Alberta, post DT, invade Greece on a humanitarian mission with guest appearance by paratrooper Susan, is hilarious, amazing fun,
Chain of pearls (anklets of light) a beautiful, visual story about Eustace and faith as he visits India, and comes to see how elephants in Hinduism allows him to better understand the Lion in his own life, . Aspects of the Narnian fandom can be horribly critical of non-Christian belief systems, asserting that non-Christians have no business enjoying the Chronicles except as a path to Christian evangelization -- ironic given the popularity of the stories worldwide. For its respectful portrayal of another belief system, this story is multi-cultural gem and Eustace is the perfect voice and vehicle for it.
