Here's an interesting variation of all the Familiar of Zero stories that've been floating around.
Of Left and Right Hands of God, by Phalanxx
The premise is that Louise summons a familiar at the age of ten. This leads to her being aware of her type of magic before the start of the series proper (along with her familiar being effectively an uncle--he's around the age of her dad). There's a lot of nice setup (and implications that Louise's family have been able to leverage the familiar's knowledge for money and power, but the story proper has juuust started. Still, I'm going to be following this one.
