The Map in the Attic

Book #39 Read in 2016
The Map in the Attic by Jolyn Sharp

Somehow I read book 1 and jumped to this book, which seems to be book #4 in the Annie Attic's Mystery Series.  That being said, there is enough backstory given that I did not feel as if I missed anything.  This is a good cozy mystery series.  In this book, Annie finds a map of some sort in her grandmother's attic.  A local historical society puts it on display but apparently it is leading to something important as someone continues to try to steal it.  Will Annie figure out who in time to stop them from taking her map?  I borrowed this book from the town library.
