Yesterday, her aunt was introduced to walking again, and she should be out of the ICU today. She'll spend a few more days in the hospital, though probably not many.
Joan is going to try to get a week or two off work so she can return to Phoenix and act as nurse. We're not expecting her to get the week of July 4 off, because she couldn't get it off for Westercon, so she may only be available for one week.
However, it looks like her aunt is going to do quite well after her surgery.
