In reference to the reaction from Argyll and Bute Council, Mr Payne reflected: "If they hadn't made the choice to ban it the response wouldn't have come in and the money for Mary's Meals wouldn't have been raised, so the cloud has a silver lining.
"I do feel that the way they handled things could've been done better and I still find it frustrating now. It was very upsetting to be treated the way that we were treated and I found it difficult to deal with that."
A trip to Malawi followed, where the Lochgilphead schoolgirl has funded a kitchen shelter through charity Mary's Meals.
She was accompanied by her parents, grandfather, brother and younger sister Polly, who thinks what Martha has achieved for Mary's Meals is "very amazing".
Named after her blog NeverSeconds, the book features Martha's story along with material from her blog and healthy eating tips for children.
