I'm currently working on a whole series of different middle grade books. I have two eleven year old daughters who are voracious readers, so it makes a lot of sense for me to write to a captive audience :). Oddly enough, my most recent book is definitely a boy book: THE BOY WHO SWALLOWS FLIES. About a bug-eating boy. The others are THE RIVER KEEPERS, KEEP IN A COLD DARK PLACE, and COUNTING WOLVES, which is young adult.
Oddly, I'm finishing them all within six months of one another so I feel like I have a lot on the go.
