She thought she could change the world...
When Lady Elizabeth Ada Lovelace, a beautiful, arrogant suffragette, purchased the 19th-century Algorithmic Engine in order to become the world's first programmer, she planned to break the shackles of inequality for Victorian women.
Until her world became that of the machine...
Instead she learns the true meaning of equality when she ends up trapped, brought down to the level of the machine. Inside the double-crossing computer, Elizabeth must match wits with a stubbornly idealistic ghost and a chillingly handsome doppelganger in the computer's endless series of mind games. But as the machine learns to become a sentient being, time is ticking away. Elizabeth finds herself falling in love with the ghost trapped in the machine. Together they are pitted in a race against the machine to escape before the Algorithmic Engine shuts down - killing them all.
Now all their worlds hang in the balance…

Theresa Fuller grew up with ghosts outside her front door. They haunted dark trees and cemeteries and were the spirits of young girls betrayed by lovers. These stories were made real by her cousins who were always recounting how just last year a child around her age had been snatched by one of these ghosts - Pontianaks. And never seen again...
Born in Singapore to Peranakan parents, Theresa was often brought to Haw Par Villa, originally a venue for teaching traditional Chinese values, as a treat. Here children are shown the ten views of Hell. She had nightmares for a week after each visit. Even today, she can visualize the demons as they tortured liars by pulling their tongues, elongating them grotesquely.
This is probably why she never wanted to be a writer. Initially.
Writers bend the truth. A little.
Theresa came to Australia for her education, met her husband, married and stayed. She worked as an analyst/programmer and later as a high school teacher. When her first son was born, she read him stories. And somehow something stirred. She remembered her grandfather and how he would tell fairy tale after fairy tale, at least ten per night until in frustration he would record them to be spared reading the same stories repeatedly.
Thus, in a strange land far away from her own family and what was familiar, she began to write. And in her stories, she could come home. To a land where boys turn into crickets and mousedeer dance laughing upon the backs of crocodiles.
Her first short story THE CRICKET SON was published in VOICES OF THE PAST, An Anthology of Stories Passed Down In Australian Families.
Her breakthrough novel is the Steampunk YA THE GHOST ENGINE, published in March 2018. It won a mentorship at the Australasian Horror Writers' Association. THE GHOST ENGINE combines her love of technology with her enthusiasm for Victorian England.
Her second novel, The Girl who became a Goddess, is a collection of folktales from Singapore. Malaysia and China published in May 2019. For this collection, Theresa drew heavily on her parents' arranged marriage.

Theresa currently resides with her family in Sydney, Australia.
