Normally, you need to complete the game to unlock the
"Book of Secrets". However, you can get into it much
earlier than that. In Chapter 4, after getting out of the inn,
go to Abnaxus's house on the City Green. Just in front of the
staircase is a flower bed. Use the organic plastic (from the Border
House, second floor) in the flower bed. The Book of Secrets is
now open nine chapters early.
