If you must know is a great story about two sisters and their mother that are trying to support each other through some very difficult situations. The suspense kept me on edge at all times and I enjoyed the point of view of each character and their so different life story. The deceitful husband, the thought decisions that Amanda has to take to protect her unborn child, the mental health issues raised by their mother and the finding her way in life of Erin , all together made for a great few hours of a Sunday afternoon reads.
