Bev of My Reader’s Block has a new challenge which sounds like fun.   You read a series of books which creates itself by each having something in common with the last book.   I’ll post what she wrote to describe it:

Evidence Trail Example: if the first book I read is by Agatha Christie, then my next book could be Arrow Pointing Nowhere by Elizabeth Daly who has often been referred to as “Agatha Christie’s favorite author.” Using “Arrow” from the Daly book’s title, then House of the Arrow by A.E.W. Mason (published in 1924) could be next and it might lead me to another book published in 1924…and so on. If you have doubts about whether your clue is convincing OR you need any clarification about the challenge at all, you may approach the bench with questions (phryne1969 AT gmail DOT com).

There are several levels of participation:
Infraction — six books read in a single chain of evidence
Misdemeanor — eight books read in a single chain of evidence
Felony — ten books read in a single chain of evidence
Capital Offence — twelve books in a single chain of evidence

I think I will go for 10 books.

Check out her site and sign up for the challenge, too.  Or she has a couple of others.  She is a mystery reader, so this is a mystery challenge, if you don’t like mysteries, you’ll have to start your own challenge, but give credit to her if you do!
