Ayesha by H. Rider Haggard

Sixteen years had passed since that night vigil in the old Cumberland house, and, behold! we two, Leo and I, were still travelling, still searching for that mountain peak shaped like the Symbol of Life which never, never could be found.

Our adventures would fill volumes, but of what use is it to record them. Many of a similar nature are already written of in books; those that we endured were more prolonged, that is all. Five years we spent in Thibet, for the most part as guests of various monasteries, where we studied the law and traditions of the Lamas. Here we were once sentenced to death in punishment for having visited a forbidden city, but escaped through the kindness of a Chinese official.
