“Oh, calamity!” This phrase is used often in response to the various annoyances, surprises and disasters that happen to the parents of the Pirriwee Public School kindergarten class. Something horrible happens during the parent trivia night event at the school, and Moriarty keeps this information secret right up until the end. Each chapter brings the reader another step closer to finding out who was killed and how, and there are plenty of suspects. In fact, there are several characters you will probably wish will be killed in some gruesome way! Big Little Lies really is a clever title, as the book starts off with an almost satirical look at helicopter parents but quickly turns into a gripping mystery as the reader learns the hidden truth about each character, making it almost impossible to put down.
