I'm writing a book called The Lost Mermaid. It's about a girl named Hazel waking up with no memory, and it turns out she has a boyfriend, Leo, but likes her best friend Eli. To make matters worse, a witch that wants vengeance on all of her mother's kids, has her twin brother Nico captured, and now she has to save him along with her friends Eli, Sky, and Leo.
The people I have called don't want to work with me, because I'm a kid. How can I get my book published despite being only 12?
