Businessman Raj Kundra, who has turned author with his book How Not To Make Money, believes a good book can be written on his actress-wife Shilpa Shetty. But he believes that for it to be unbiased, someone else should write it. ‘She has so many achievements in her life that a good book can be written on her, but I won't be justified in writing it. I will be more biased,’ Raj, who married Shilpa in 2009, said. ‘I think an outside writer should do it,’ he added.
