Her story starts at the Bishops' arrival in America. It ends at his deathbed. In between, we meet all walks of life, all religions, all the blessings and hardships. The physical landscape of the country is described to contrast and sometimes to explain the land's inhabitants. The difficulties of a mission are insurmountable but a start has to begin. Even the priest's innermost feelings of loneliness, despair, hopes, etc. are described.
I recommend this book to all. Much of the duties and liturgical ceremonies are still in practice, so it's not outdated. Good read.
