What a fun book to read. This is the third and last book in a series of three books in the Trains to Impossible Places series. I hadn’t read the first two and realized when starting this story that something else happened prior. But it is all good as I quickly understood what was going on. Suzy, a young girl is also a deputy postal operative for the train mentioned above and is trying to convince her parents to allow her to take another journey to return a really overdue book to a city that no longer exists. To allow her, they take the journey also. What a trip they take us all on. It is an enjoyably book for kids of all ages! ( )
