Author Rod Duncan is celebrating after signing a deal to complete his trilogy of books in the Gas-Lit Empire series.
The fantasy series is set in a steampunk world of alchemists and secret societies but is also rooted in the Victorian architecture of Leicester.
The first book in the series, The Bullet Catcher's Daughter, was released in September this year and won the Leicester Writers' Norman King Award.
Sales have been going through the roof in recent days after it was promoted as "daily deal" on shopping website Amazon.
It topped the Amazon fantasy novels chart and reached number 42 is the overall book charts, selling thousands of copies worldwide.
His publisher, Angry Robot, plans to release the second book in the series, Unseemly Science, in May 2015.
Now they have announced they will also be publishing the third, The Custodian of Marvels, which is set for release in spring 2016.
Rod, who lives in Glenfield, said: "Angry Dog are specialist sci-fi publishers and they're the perfect publishers for me.
"They're one of a new breed of publishers who are very aware of their audiences and I'll be going to events and festivals.
"That's one of the joys of writing in this genre - you have a very enthusiastic audience who like to go to conventions."
The Bullet-Catcher's Daughter got rave reviews from reviewers around the world.
It tells the story of Elizabeth Barnabus who lives a double life, sometimes pretending to be her own brother, a private detective. She is trying to solve the mystery of a disappearing aristocrat and her life, and the course of history, begin to change.
Among the reviews for the first book was one in Publisher's Weekly which described it as a "strong supernatural mystery'.
The late Graham Joyce, who lived in Knighton, Leicester, and died in September aged 59, described it as 'a superb book'.
He said in his review: "The Bullet Catcher's Daughter is itself a magic box pulsating with energy.
"Compulsive reading from the get-go, the blend of steampunk alternate history wrapped in the enigma of a chase makes for first-rate entertainment in this finely crafted novel."
Entertainment Weekly's review said that Elizabeth Barnabas felt "fresher and more engaging than the typical steampunk protagonist".
Fantasy Faction's review stated: "It's fair to say I was smitten by The Bullet-Catcher's Daughter.
"Rod Duncan's talent has combined inventive plot and characterization to create a smart, amusing and fascinating tale that had me reading long into the night."
Angry Robot publisher Marc Gascoigne said: "In Elizabeth Barnabus Rod Duncan has created a wonderfully engaging and resourceful heroine and in the Gas-Lit Empire a tremendous alternative version of English history.
"Angry Robot has Unseemly Science, its miraculous sequel, on our list for Spring 2015 but we couldn't leave the story there, so I'm delighted to have snapped up another instalment, The Custodian of Marvels."
