Her first book, A Man in the Palm of Your Hand, made a real boom, becoming a major regional bestseller overnight. The idea for the book came when her best friend, disappointed with a bad date, stated that someone should write a manual for men. Given that she was facing the same problems finding a quality partner, which is why she spent years and years researching and understanding male-female relationships, Nelly decided to write a manual, but this time – a manual for women. The idea was simple – to help women achieve everything they wanted when it comes to love, explaining what men really want and think. The idea was to reveal secrets of a male mind and therefor simplify communication between the sexes. Her dream became reality because her book published in July, 2015, helped tens of thousands of women to change their love lives and became a huge bestseller in Europe.
