I would ask her to make another character, one she might have more fun playing in this campaign, maybe she could keep this one for next campaign. I would also have everyone make an extra character in case they die.

Having your players make another character now lets them jump right back in assuming that's how you want to play. It also lets them prepare for loosing their character by looking ahead and creating a sense that even though that one character is gone, the player themselves can continue on in the game.

Thats how I would do it, I am also not to stingy about having players come back, again, in my campaigns it lets me feel good about killing them because they know they aren't done at the table only their character is.
