I'm so glad you enjoyed it! My sister previewed it for me during its progress and had printed it out to take on a trip; she started reading parts as they came out of the printer and ended up reading the entire thing before she even left, so I'm glad she wasn't the only one drawn into it.
I really enjoyed writing Tom here. I don't think he was evil enough in DH and I wanted him to have a bit more interaction with Harry. I'm glad you liked it, and thanks so much for taking the time to comment.
