"Get Us Out of Here!" by Nicky Eltz features Maria Simma speaking about Heaven, Hell and Purgatory.

This is one of Immaculee's favorite books and she urges everyone to read it.

"Dear reader, What you are now holding is a most interesting book. The world beyond is speaking. It is offering advice, asking for help, and giving answers. It exists and speaks about life - our life here and of possible consequences of our behavior. It tells us that it is not the same to be humble, loving, good, merciful, loyal and honest as it is to be proud, loveless, bad, merciless, betraying and dishonest. At death this is not forgotten but rather remembered in total clarity. Not only is the punishment, or better yet the cleansing, spoken about; but also the length of this cleansing and so very much more!! ...all personal doubts disappeared once I too had met and spoken with Maria Simma. She is true..."
