A quick read - only took about 45 minutes, so that's the positive.

However, this story was frustratingly shallow - and not because we never find out who killed the sister, but for a book that was said to explore loss after a tragic death.... it really didn't? There were hints of it but where this book had potential to really follow down a certain path, it would take one step down that and then scurry off to the next short, dead-end path.

The characters were not explored - wasted pages during a one sided phone call to hint at the potential killer (pages that could have been used to explore the sister's need to look like her deceased sister, the replacement baby etc), but were just there to tease the reader into a frustrating dead end.

Shame, because the idea had such potential but poor execution.
