Waking up in the morning with a headache is bad enough, but waking up with a headache and then being beaten up by your brother, or now your sister? That's what happens to Rick the very first day in what he soon learns to be called the Multi-Stream, and it's only going to get worse from there.

After his royal beatdown, Rick soon learns that he is a 'Chosen' one, and is participating in a game to win The Big One, and it seems that his new sister not only thinks Rick is after it, but is also after it herself, as well a bunch the other Chosen. Whether he wants to get The Big One or not, he knows he will have to fight and master the powers all Chosen have...

....even if those powers come with some serious side effects...ones he isn't sure what to feel about.
