These are a variety of shots of covers, backs, etc.
I am offering one of these here books (from this series) as my second official blog prize!
The clue is:
Thursday's (real) daughter.
To win you need only be the first person to enter the correct one word answer in the comments of the next post I put up that has the name "Jasper" in it. This will happen in the next week some time.
Good luck if you want it.
