Rate this book
Callum and Troy are on the verge of a scientific breakthrough that just might change the world. The cure for baldness.

But the pair haven’t planned for side effects. Callum, as test subject zero, finds not only is his hair growing, but his body is changing. He becomes softer, prettier, girlier. And then the urges start...



Callum and his best friend Troy are on the verge of a scientific breakthrough that will make them both rich and famous, and might just change the world. The cure for androgenic alopecia. The cure for baldness.

But when Callum, whose hair loss inspired the projects, becomes the very first test subject, he encounters some unintended side effects. Not only does his hair grow, but his body undergoes subtle yet undeniable changes.

Initially, the metamorphosis is gradual and minimal, so the pair push on, collecting as much data as they can on their new formula, but eventually, the changes become too much and too many to ignore. Troy, hesitant, wants to pause the experiment. Callum though wants to push on, and he ignores Troy’s attempts to make his stop.

And then the changes become more obvious. Callum becomes softer, prettier, more feminine, he can no longer deny the truth. He’s gone girly, and he can’t deny the exciting allure of his new body, especially with all his new desires.

Troy, reviewing the data, reassures Callum that the side effects are temporary and reversible. They just need to work out a counter formula, and for that, they’ll need to put their heads together and focus. But Callum finds it increasingly difficult to concentrate given how hot his new body feels.

As Callum’s changes become more dramatic, brazen and sensual, and as his urges become stronger, he begins to wonder if there isn’t some useful data to be gathered about his transformation. And if he has some fun at the same time what harm could it do? He just needs to be careful. Especially given what Troy said about the changes becoming permanent.

It’s just a little fun, for science. And it’s not like he’s going to go all the way… is he?

One kiss - “I was enjoying it” says it all

I had to get my breath under control after the rest of the sequence once was over. I feel a lot of people will read that chapter (I won’t say which one) and they will reflect thinking or saying out loud yeahhhhh that brings back memories and emotions.
