Buckingham made her public debut in the field of juvenile literature.
 In 2007, at the age of twelve, she crafted with her younger sister a short story, chronicling the adventures of the princess Lilly and her "lost" little sister, Blossom.
Inspired by a L. Frank Baum book, The Lost Princess by Celeste and Carmel Buckingham was published on October 1, 2007 by Divis-Slovakia.
Shortly after its paperback release, the girls' father summarized the result for Amazon.com, stating in his review: "The story is about the kidnapping of the younger of 2 sisters and how the older sister is able to find her and bring her back to her family.
The characters have many adventures and go thru [sic] many difficulties before their family is reunited.
The characters must grow and become stronger thru [sic] these difficulties [...]."
Their picture book illustrated by Georgina Soar would not attract particular attention, and neither of the daughters would reprise their attempt in the literary genre.

Instead, Buckingham gradually started writing acoustic songs on her own, some of which would later result in a child "album", while with her sister she set up their off-stage band Anchorage, named after the city in Alaska they once resided in.
One of her first rough demos, "Blue Guitar", had reportedly been written when she was twelve.
Despite developing a passion for music in her pubescent years, she was said not to have been a happy teenager.
When questioned in 2013 by Radka Červinková from Mladá fronta DNES, she disclosed that it was mainly due to a struggle over ongoing concerns with her self-confidence at that time. "
Guess it's hard to believe, but there were times when I felt so alone, because I thought I'm not good enough for anyone, that everything I do is wrong and I'll never accomplish anything.
Maybe it was puberty but between the twelfth and fifteenth year I was a constant gloom-and-doom, and [I] wouldn't know what to do with myself.
Only one thing saved me – the idea that I'm a quite good singer."
Until the time her career-making moment arose, she was educated at the Forel International School, which was founded by her own mother, a Bahá'í devotee.
