Living in the small town of Heavenly, Pennsylvania, Claire Weatherly has come to admire the Amish for their wholesome, honest way of life. But she also knows that nothing is as simple as it seems—especially when murder disturbs the peace.

Claire has always been game for a good puzzle, so when she hears that Mose Fisher has made one of his famous corn mazes, she can't wait to walk the paths and test her skill. But she'll have a much more serious puzzle to solve when, deep inside the maze, she discovers the body of Amish dairy farmer Harley Zook.

It won't be easy for Detective Jakob Fisher to investigate a murder on his own father's farm—not after being shunned by the man  for leaving the Amish community and becoming a cop. With Mose himself as a suspect, and old family secrets cropping up, it's up to Claire to help catch the killer before she finds herself at< a dead end.
