The Library of Time Book 3

Fast-paced roller coaster ride though time and space. 

When Sam heads off to the planet of Atenua to meet his father, Annie is left to take care of their daughter and the sudden influx of people who want to borrow books from the library or have a Tarot card reading. When Jack arrives with a sudden need to head to the 1800's Annie is forced to go with him. But it is the trip back that suggests a change in the way things work inside the library's doors. Who is the man who has suddenly appeared like a doorman? And why is he there?
