Serena

Was Maya Delaney's best friend until she apparently died by accidently drowning in the lake. She was a subject of The Edison Group.

Excerpt from The Gathering:

Serena stood on the rock ledge twenty feet above the lake, singing in a voice known to bring tears to the eyes of everyone who heard it. Everyone except me.

"For God's sake, Seri," I said. "Just dive already."

Serena stuck out her tongue and shifted closer to the edge, toes wrapping around it. She bounced there, blond ponytail bobbing, cheeks puffing. Then she dove. It was, as usual, an effort worthy of the Olympics, and she sliced into the water so smoothly that barely a ripple pinged across the glassy surface.
