A big prayer request.

The past week has brought one of the highest of highs and one of lowest of lows. More on the good news later, but for now, it is with a heavy heart that we're asking you to pray for a little girl in Arizona who was diagnosed last week with a PNET.

Several of you e-mailed/Facebooked to let us know, and we would have posted about Kate McRae before now, but we wanted to make sure it was okay with her family first before we publicized their very personal struggle. It has also been difficult to simply type the words. News of Kate knocked the wind from me. Not another child, God, please not another family ...

This—right here—is why we were in the fight . She, just like Kyrie, was a completely healthy, normal child one day, and within two weeks, she's recovering from a crainiotomy and in preparation for a chemo plan. It is for her parents who are exhausted and frightened and wrenched with worry that we fight. We know this place. We know this anguish. We know the constant prayer that is behind every breath as you sit in PICU. We know that perpetual support and prayers from anyone is the only thing that resembles comfort when you're in the fight of your life.

We're with you, Kate. We're with you, too, Holly, Aaron, Olivia and Will. We're right there with you.
