I had previously read and fell in love with "PS I Love You" and so was anxious to read "Where Rainbows End". At first I was unsure and dubious about how well the unusual writing format would work but after a few pages I found it an interesting and unique way of writing which adds to the books appeal. The whole book is a rollercoaster of emotions. I found myself laughing out loud, crying, gasping and even yelling out loud at charactors. The charactors of Rosie and Alex were very realistic and believable and you are left feeling as though you have experienced their lives with them. A recommended read for all.
