This was a hard and emotional read but kept me hooked. A group of 5 teenagers spend an evening at a party and then drive home - there is a crash and all of their lives are altered forever. Its not only the teens that are affected but the rest of their families. This is a story of grief, friendships, families and forgiveness, relationships are tested to the limits . The chapters are short and at times hard hitting and emotional. As the story progresses you get to hear the back stories and as the name suggests how everything can change in one split second. This would be a good Bookclub choice as the stories throw up lots of questions. A hard hitting but very well written book that will stay with me .
