New Wellington born fairy tale Promised Land is for sale online and in some bookstores.

Like every tried and true fairytale, Promised Land had romance, a villain and in the end, love overcame hate.

The only difference is, this storybook seeks to normalise multiculturalism and homosexuality for young readers.

Wellington writers Chaz Harris and Adam Reynolds have released their much hyped adventure and medieval love story, Promised Land, on Valentines Day, after raising more than $40,000 to fund the project.

SUPPLIED Authors Adam Reynolds and Chaz Harris spent over a year working on their latest fairytale.

The heroes, a bi-racial gay couple from different necks of the wood, team up to fight the Queen's evil new husband.

The story's Queen is also "a sword wielding bad ass," co-author Chaz Harris says. There are no damsels in distress in his book.

SUPPLIED Queen Elena, she's "a sword wielding bad ass", Harris says.

He also said it was important to write a book that wasn't about the subject of diversity, but rather displayed diversity in the story.

Promised Land is released online and in some bookstores on Valentine's Day. Harris said it was targeted at five to 10-year-olds, but included some more complex words to keep older readers and listeners entertained.

"If you're a teenager and 12 or 15, and you've realised 'oh I'm gay', you can look back at this," Harris said.

SUPPLIED The authors hope their Promised Land world can be used to tell other diverse stories.

He hoped his world, The Promised Land, would spawn new creations and stories – even if he wasn't writing them.

Harris was looking to tell other stories, featuring diverse casts, in an attempt to normalise diversity for young generations.

"We have a responsibility to provide that voice, we want other people who can authentically be that voice," he said.

SUPPLIED Promised Land follows a young couple, a prince and farm boy.

Harris said they wanted to create this book to give LGBT+ children a voice in their stories, as well as making it a normal experience for straight children to see diversity.

"If you don't see yourself in stories, you don't see yourself in the world," he said.
