I wasn’t too sure about the premise, but heard good things about this book. It really grew on me as I listened. A couple of times I had to sit in my car so I could listen to the end of a ‘letter’.
I generally don’t like it when there are too many narrators but in this case I loved it. The main characters were so vividly portrayed and, like someone else mentioned in their review, sometimes I was waiting to find out when their next correspondence would ‘arrive’.
Highest recommendation from me.
