Summary:

The world is on the precipice of war, albeit nobody yet realises how close it is. 

 

The global pioneer of growth and shrinking technology Pharmadon, a conglomerate of Pharmaceutical and tech companies, has led the charge on the development, and is close to signing an agreement with the United States, United Kingdom and European Union on a contract scale of an unspeakable magnitude. 

 

The CEO of Pharmadon, the intelligent and ambitious Hailey Hewitson has let nothing stand in her way to her global dominance aspirations. 

 

All that potentially stands in her way is their US and European competitor Pharma-Kleine and their Eastern competitor Kilternan-7. 

 

Pharma-Kleine tends to play by the rules, they follow compliance and best practice; which is why they have fallen behind in the race. But Kilternan-7 knows no bounds. They have marked Hailey as a target, they send a team of specialist agents to secure her unique technology…

Summary:

The world is facing disaster! The explosive Mount Uproar is set to erupt any week now and cause widespread devastation, potentially ushering much of the world into darkness. Thankfully, the ingenious Grand Technologies company has devised a solution: grow a person very, very tall. The giant's task is simple. They'll march over to the volcano, stomp it to dust, and be celebrated globally as a hero who saved so many lives. But the chosen savior has a lot put on her shoulders, more than she realizes. She’s become a powerful new force of nature. Perhaps there's more going on here than meets the eye as people seek to harness her energy, and her courage, intuition, and resolve will be put to the test. She will have to decide who she can trust.

Summary:

Get ready for one of my longer books - a full novella of size-shifting fun with an emphasis on character, noms, and a little rare sauciness - find out what happens when two hapless lesbians get caught up in a world of size-warping forbidden tech! This is 20 chapters long, which I plan to release steadily in full here. (It is also available in eBook and paperback already.)

I've had an itch to share something a bit more substantial on here, and with my book sales channels generally drying up a little, I'd love this more ambitious project from a few years back to reach more people (I'm pretty sure this book doesn't even show on certain booksellers unless you're really specific with your search).

Here's the blurb:

Violet and Nova are ready for some big changes. A lot of people are going to get hurt.

Violet is fed up with her boring life and society in general. Angry at her latest commute, she bumps into Dr Harper Roan at just the right time.

Violet accidentally takes something of Harper’s: a device with the incredible power to shrink things – or make them grow. And with a little encouragement from her bombastic partner Nova, Violet realises it might be just what they need to shake things up.

Starting by punishing anyone who crosses them.

But the shrinking device comes with complications: Harper’s dangerous employees are out to recapture it, each use connects to something terrible, and Violet is getting new, voracious desires . . .

Just as well this hapless couple are hungry for a fight.

From miniaturising victims to earthshaking growth experiments, a bit of wild fun quickly turns deadly. If they can survive the horrors they’ve unleashed, how far are they prepared to go?

One thing’s for sure: things are about to change in a BIG way.
