I read "Walking on Water" after my son had Open Heart Surgery in 2007. He was a Tet baby and was operated on at UofM. I witnessed firsthand what miracles Peds Cardiologists work & I can only imagine how much pressure you were under....not to mention the helplessness you felt at times. I cannot say that I was shocked to hear about your death, but I hope that you have found the peace that you so desperately wanted. Please guide all of the doctors and nurses as they work on our precious angels. Blessings to your family.
