HMV has started selling a range of Minecraft fan fiction.
The Battle for the Nether and Invasion of the Overworld from the Gameknight999 Adventureseries by Mark Cheverton were first stocked by the retailer in October after they were published in September.
And they were amongst the Minecraft products that helped boost HMV's merchandise sales over Christmas.
We are really pleased with the performance of the Gameknight999 books, along with our full range of Minecraft merchandise,” HMV's head of technology and games Phil Browes told MCV.
Our Minecraft books and merchandise have all proved very popular and have been a sales highlight over our peak trading period and into 2015.”
