December 1, 2009 - November 30, 2010
Here's what Kathrin says:
The rules are easy:
1) Pick a couple series you already started and now want to finish (meaning, you'll be all up to date with the series when it ends).
2) Read at least 4 books, more are also okay, of course!
3) Crossovers with other challenges are always okay.
4) Post your review of the books on your blog or in the comment section, no matter how long. If you post the review on your blog, please post a link to the review in the comment section so that everyone else can check out your review.
5) Have fun!
