Theme – Forgiveness – Year 13
Let me sing you gentle songs by Linda Olsson

Their unusual and tender friendship flowers, as they slowly and carefully reveal their life histories and sometimes heart-rending pasts.

Story of a girl : a novel by Sara Zarr.

Touching Spirit Bear by Ben Mikaelsen. After his anger erupts into violence, Cole, in order to avoid going to prison, agrees to participate in a sentencing alternative based on the native American Circle Justice, and he is sent to a remote Alaskan Island where an encounter with a huge Spirit Bear changes his life.

Ursula Le Guin always writes thoughtful and thought-provoking explorations of human relationships and ethics - and good stories too! 'Four Ways to Forgiveness' is a set of linked novellas exploring a scifi society with definite similarity to aspects of the ex-slave owning USA in particular. The characters overcome divisions based on caste, gender and race. This book will probably appeal more to girls, given the way it's driven by personal relationships, but reasonably good male readers should also get a lot out of it. You might make a case for the Earthsea books as well, which are very accessible but might need a bit of justification to fit the theme. (Might also need to check they are of acceptable difficulty - I think they are, being books that can be read at different levels.) However, while forgiveness is not explicitly stated, it underlies the restoration of good personal and social relationships. (eg Ged's acknowledgement of his mistakes and failings in 'A Wizard of Earthsea' and the overcoming of prejudice in 'The Tombs of Atuan'.)

The Count of Monte Cristo by Alexandre Dumas - as a case where forgiveness is NOT given. The result is an empty pursuit of revenge that doesn't do anyone much good, though I shouldn't think that was Dumas's intention.

Emma by Jane Austen. It's hardly a central theme, but the setting right of all sorts of relationships is fundamental to the happy ending - eg between Emma and Miss Bates. Emma's realisation that she requires forgiveness is a pivotal point.

Shakespeare's 'Much Ado About Nothing' hero does NOT forgive Claudio. Raises the interesting point: are there things that cannot and should not be forgiven? Or not lightly, anyway?

The Tulip Touch by Anne Fine- might be used to examine that idea, and also where responsibility for wrong-doing lies: who needs forgiveness, the actual perpetrator of an active wrong, or the people who through different degrees of passivity allow it to happen?
