As Shakugan said, have her try NIER. Its a great game. The battle style is more along the lines of a hack and slash since its an Action RPG (similar to DAII), but it has some really good character interactions, customization, and what not. Not to mention the fantastic story, setting, and OST.

You can't interact with the character the same way as in Dragon Age (dialog choices and what not) but they do alot of interacting with eachother on their own, so it would still probably keep her attention.
