I've been following the conundrum of Kristi Diehm who publishes a small YA publishing blog called The Story Siren. In the midst of strong allegations with regard to plagiarism, Ms. Diehm issued an apology/explanation on her blog, here. And I just read what appears to be a clarification of that apology, here.
No comment from me. The "clarification"...or second apology...sounds sincere. If you notice, when I write blog posts I try not to begin a sentence with "I think," or "I feel." I try to stay away from hearsay as well.
I don't know Kristi, but I wish her well.
