Rules of the road by Ciara Geraghty

The simple fact of the matter is that Iris loves life.  Maybe she's forgotten that.  All I have to do is remind her of that simple fact.

When Iris Armstrong goes missing on her 58th birthday, her best friend Terry, wife, and all-round worrier, is convinced something bad has happened.

And she's right, her glamorous, feisty friend is setting out on a journey that she plans to make her last.  The only way to stop her is to join her, on a road trip that will take Iris, across the Irish sea and into an adventure that will change their lives.
