Scarlet and Ivy” is a series of young adult novels by American author Sophie Cleverly. The first novel of the series was “The Lost Twin” a highly popular and critically acclaimed novel that was such a success that it spawned an entire novel series that is still ongoing. Sophie Cleverly was born in 1989 in Bath, a small town in Maine. Growing up, she was very much interested in children’s literature and read the likes of Neil Gaiman and Terry Pratchett who incidentally write both children and adult literature. Her “Scarlet and Ivy” series has been greatly inspired by “The Graveyard Book” and “Coraline” by Gaiman and “Tiffany Aching” by Pratchett. What she especially liked about these novels was that they were beautiful, sad, scary, and funny all at the same time. She was quite the reader and would visit the city library and borrow as many books as she could to read during the week. In addition to these, she would also take as many books as she could from the older classes bookshelves, as she had already read all the books in her class. It is not surprising that her novels have been compared to Nancy Drew as she absolutely loved to read the likes of The Famous Five, Nancy Drew, The Baby Sitters Club and Goosebumps. Of these series she collected and read nearly every title. Aside from detective fiction she also read a lot of mystery novels which made her believe that she wanted to become a mystery author when she grew up.
