The complex story is told in two alternating tracks, with the first set in a lightly fictionalized late 60's Berkeley, and the second set in Turow's present-day Kindle County. The main character, Sonny, finds herself the judge of a murder trial involving people she has known for twenty years, and must decide it without the assistance of a jury.
This book is very long and complex. You will need patiences for a story to get to the point. But, Turow writes extremely well and ranges widely, taking on gang culture, judicial corruption, and the ever present political manipulations. And he always has very interesting character at the center of his tale. I would suggest this not be the first Turow book you read.
