Just recently, on Twitter, followjackheath tweeted:
"[Jack Heath] isn't sure what you say when a thief who pretends to have supernatural powers is hunting you. But he has a deadline to figure it out."
This suggests that the next book has someone in it being hunted by a thief who pretends to have supernatural powers.
Hints we've gathered about the new book:
1. Coming out in 2010 (Because he does one a year) and possibly August.(Because that's when the last one came out.)
2. It includes a theif who pretends to have supernatural powers.
3. It's called Hit List(at the moment) and it's centering around Ashley and Benjamin from Money Run. (We know this because it says:
William: Working on anything new at the moment?
Jack: Ashley and Benjamin’s next in-over-their-heads adventure. It’s called Hit List, but that may change.
And this was on a 'blurb it' website.)
Uh, Jack Heath, this is reminding me of Matthew Reilly's Scarecrow already. Just, whatever you do, CUT THE GUILLOTINES! (Pun Intended. :D)
