Big Little Truths by Liane Moriarty  

After all their big little lies, what happens next? The gang is back. Madeline is planning her 50th birthday party. Jane is happily married to Tom (isn't she?). 

Celeste is haunted by memories of her dead husband, and troubled by her very alive mother-in-law. The kids are no longer kids. And things are falling apart. It's been ten years since Perry Wright fell from a balcony at the Pirriwee High trivia night but best friends Madeline, Celeste and Jane are still shadowed by his death. When an anonymous package containing a severed finger arrives at the school, and a man in a green Volvo is seen lurking around the kids, everyone is uneasy. 

Is the finger pointing to a mystery, or even murder? A lie masquerading as the truth? Or a secret about to blow up their lives? What is clear is that the truth will always hurt someone.
