I picked up this book to read on the weekend thinking "140ish pages... nice and short... maybe I can recommend it to my Year 7s". Maybe not. I had several issues with this book. Firstly, I didn't like the ending (I hate not knowing what happened to so-and-so, but maybe that's just me). Secondly, I don't know how well this book translates across to the world of 2012 teendom. For example, some of the dialogue was quite old school/amusing. Did teenagers (or anyone, for that matter) really use the word "rad" back in the early 90s, as in, "We had a rad time"? Would today's teenagers even know what a penpal is? If anything, the concept of putting pen to paper and actually 'writing' a letter/waiting a week to receive one in the mail would probably seem quite alien to most 16 year olds... not to mention the fact that most teenagers are used to sharing their innermost thoughts on the most public of forums (i.e. Facebook) and there is no such thing as delayed gratification. At the beginning of the book, I also found it difficult to distinguish between Mandy and Tracey, to the point where I had to keep checking who was who. It wasn't until we found out the truth about Tracey that their voices became a little more distinct. Thank goodness for the big reveal though, because I wasn't sure I could read endless letters about potential boyfriends, etc. Finally, why is it so hard to find a kind/trustworthy adult in John Marsden books? Despite the fact that this is supposed to be Contemporary Realistic Fiction, I found that "Letters" presented a not-so-realistic take on what adults are actually like. They're not all completely unreliable and they don't all set out to ruin kids' lives. Some of us are actually okay.
Now for the 'likes'. I liked the way the two girls didn't hold back and openly criticised each other's letters (e.g. whether or not they felt they were getting the right response to a previous letter). I also liked the way that they both seemed willing to process/accept this criticism, when many others would have thought "stuff you" and stopped writing. Even though it only existed on paper, their friendship and loyalty to each other was tested to the limit. From an educator's perspective, teachers could certainly use this text to explore the nature of friendship, family relationships and domestic violence.
Overall, this book definitely becomes more interesting once the true meaning of the word "inside" becomes apparent. Whilst I would recommend this book to Year 9-10s, some of the prison-related imagery is not particularly age appropriate for Year 7-8s. Not the greatest insight I've ever had into the teenage mind, but worth a read.
