Yancey lives on the Fridge, his name for the Scientific Research Solar orbiter Icarus4 that is home.

He's a typical 14 yr old teenage boy, mad about gaming, avoids homework, awkward around girls and can build a complex holographic human to help in his video games, complete with emotions, feelings and solidity. Plus the Hologram is his twin almost, a badly behaved alter ego.

But the Fridge is more than a solar orbiter, unbeknown to Y., it's an important anti alien incursion weapon and someone and something is trespassing in Earth Space.
Gali is... troublesome, she hates being on this tin can of a space ship. Running away seemed a good idea at the time. Now it's late at night, she's alone, at the bus station waiting for transport to the Hermes7, a touristy spaceship and she is going to be robbed, except there's an old bloke there who doesn't appreciate crime in his neighborhood and has some weird ex spy agent gadgets in his possession.
Forced together because of an alien threat, Y., Gali, the stupid hologram and the old man discover that they don't get on that well, giant bugs are real, raspberry jelly shape shifting beings are tyrants and holograms can be stupid.
But then there is the giant, hairy, four armed Idesian warrior. He seems fun, loves a good BBQ and thinks everything will be fine.
That may be true if the Department of Secrets are not involved.
They're involved
And as long as an inter-dimensional mythical evil doesn't appear.
It appears!
