An autistic child is "stuck" in his first wizardly ordeal against the lone power. Kit & Ponch are sent in as backup. Nita gets creepy dreams from the kid's subconscious mind but is so absorbed in grieving from her mother's death of cancer that she can't pull it together to help Kit...can she?
I really love this entire series, beginning with the classic, So You Want to Be A Wizard?...
If you'd like to try a more adult themed offering from Diane Duane, try the excellent short story, Lior & the Sea. I think it is only available in the Andrea Norton tribute book, "Moonsinger's Friends", but you could likely try searching for it on the net, just to see if it appears elsewhere...but anyway, its one of my fave stories of all time...reminds me of the sort of thing you'd usually find in a Marion Zimmer Bradley Sword & Sorceress collection. Romance & sorcery, elementals...great story by Duane.
It felt good to get back to this series. I was worried at first because Nita and Kit weren't working together and I hate seeing them apart - alone - but that was really what this book was about - helping Nita (and Kit also) to realize that they do need to work together and that they can't shut out life because of grief or other such reasons.
