Never stop asking questions- ever!!!
Some of the questions you ask will be answered towards the end of the book.
I have to do a lot of work on part one, as I know the character development is thin, to say the least!- I was playing with ideas at first, then got into it more, as it looked like the book might actually happen!
"have any of the key characters had to sacrifice something just to be a part of the Meddlers"
There is a VERY strong motivation for them to stay with the team- this comes out later, but has been hinted at
Good questions!
