It was one deal in many rejections for Amanda, who had almost given up hope after sending her manuscript to "everyone" she could think of.
And she admits that if the deal hadn't come along so soon, she would have been back to working three jobs again to make ends meet.
Her first book, Poppy Day, was published in 2012.
But even after clinching her deal, Amanda said she still had to work a year to 18 months in arrears.
She said: "It wasn't until 2013 after I'd written two or three bestsellers, that I got my first big cheque of about £50,000 or £60,000. Amanda now writes four bestsellers a year and makes an annual salary of £1 million. But to produce that much work comes at a price.
She sits down to write for 10 hours a day, seven days a week and even makes sure she works on Christmas Day.
Amanda is now a millionaire, with her books sold in 22 countries, and many making the bestsellers lists.
Her earnings have built up quickly, but she keeps half in a separate account, so she can pay her taxes.
