My son and daughter in Australia have not been speaking to each other for a long time. A few months ago I began using the prayer card of Dora del Hoyo every day asking that they be reconciled.
Out of the blue, two days ago, my wife received an email from my son to say that they had been in touch with each other and had talked for a good time on the telephone. This was a very difficult, long standing situation and a reconciliation seemed very unlikely.
I have no doubt that the good result was obtained through the intercession of Dora del Hoyo.
