I just finished reading Every Secret Thingby Ann Tatlock, and I give it a 5 out of 5 stars. 

The book follows main character, Beth Gunnar, as she returns to her high school to teach English and the many characters in her life.  There is a perfect balance of current events with flashbacks to her high school days.  Characters range from her favorite pupil, Satchel Queen, to her high school friends.

The overwhelming theme is the nagging feeling she’s left with after her high school English teacher apparently committed suicide.  The mystery and its emotional baggage weave throughout the pages drawing the reader deep into the psyche of the characters and how that taints many of their present relationships.  The ending to the book is great too, giving the reader plenty of closure with no nagging loose ends waving in the wind.
