I'm glad you liked it. In general, I tried to make many of the characters the opposite of canon, like loving Dursleys, Muggle loving Malfoys...just to have a bit of fun. I've never been able to see a canon type Draco with Hermione, so this was a good opportunity to get them together. I liked doing a sexy, flirty Bella the best.
But I couldn't get Tom to quite cooperate, so yes, he turned out to be untrustworthy and a bit on the crazy side. Even though Snape is vengeful and abusive, I didn't want him to be the true villain of the story, so Tom was elected.
Thanks so much for taking the time to comment! I'm slowly working my way through all the fics, so I know how much time is involved in reading, especially a longer fic like this one is.
