I'm sorry to say that it's very unlikely that there will be more Sam books, as my then-editor effectively killed them. Sorry to give you bad news! But you could try my chick-lit books, or my YA mystery series, which starts with Kiss Me Kill Me and has a heroine very like the young Sam in many ways. I also write racy 'bonkbusters' under the name of Rebecca Chance, and any Sam Jones fans will probably enjoy those quite a lot!
