Adornetto is the daughter of an English Teacher and a Drama Teacher and attended, in her own words, "many" schools including MacRobertson Girls' High School, Ruyton Girls' School and Eltham College. She says she was 13 years and on school holidays when she decided to become a recluse and started writing her first book for young adults, entitled The Shadow Thief. She did some research into Australian publishing houses, making sure she followed all the submission guidelines exactly, and then sent her manuscript to HarperCollins. She has said that it took HarperCollins about twenty weeks to get back to her asking to publish her book.

In 2006 Adornetto won the State Legacy Public Speaking competition.

Adornetto has featured in Fairfax publications commenting on youth issues such as sex and alcohol consumption .

Adornetto's completed books are The Shadow Thief (published 2007) and The Lampo Circus (2008), and Von Gobstopper's Arcade (2009) all published by HarperCollins.
