This challenge is run by Alyce by At Home With Books. If you click on the picture, it will take you directly to the post where you can join the challenge.
Here is the information regarding the challenge straight from Alyce's site.
The idea behind this challenge is to read works by authors who have been recommended to you time and again, yet somehow you haven't managed to read any books by those authors. These are the authors that everyone else tells you are awesome, thus the "Awesome Author Challenge" title.
The challenge starts January 1, 2010 and ends December 31, 2010.
Crossover from other challenges is allowed.
Choose the level at which you would like to participate, post about it and come back and leave a link to your post in Mister Linky.
Titles and authors do not have to be predetermined, and can change at any time.
Books can come from any genre or reading level, the only requirement is that you have heard great things about the author, but haven't yet read any of their works.
Easy: Choose three authors and read at least one title from each author.
Moderate: Choose six authors and read at least one title from each author.
Challenging: Choose ten authors and read at least one title from each author.
Over-Achieving: Anything over ten authors.
I am going for the moderate level and hope to read a book from each of the following six authors.
Charles De Lint
If you want to join in, then there is plenty of time as it doesn't start till January.
