An Alien Abduction

This book is a "choose your own adventure" where, as it's probably obvious, you, dear reader, get to make all the decisions!
The MilkyWay is in grave danger, threatend by a ravaging, cunning race, the Cronites. You abruptly face the dizzying new prospect that your tiny bubble of Teenage Horror Show you've been living for the past few years is really just a tiny speck in an infinitely bigger reality. And had you never been caught up in the confusion you would've never learned the truth of it all. Never known why, until it was too late.
Do you have what it takes to stop the Cronites and save the galaxy?
I suppose all there is left to say now is have fun and try not to die ;)
