I DIED.  For forty-two seconds I died.
They were operating on me—why isn’t important anymore—and it was a simple surgery, everyone said so.  My dad didn’t even take off work.
Breathing, breathing, not.
I can picture it.  The ‘oh, no, ‘ the scurrying around, the paddles on my chest, thwump.  Clear!  Thwump.  Beep beep, beep beep, she’s back. 
Everything back to normal.
THEY DON’T KNOW ANYTHING.

Cara Campbell thought she had it made:  star athlete, popular student, winner.  But when she dies during surgery, she sees something she knows no one would ever believe.  The doctors manage to revive her, but what happened during those 42 seconds of death has changed everything.
Now Cara is having a hard time adjusting to her former life.  None of her friends or accomplishments matter anymore.  What does matter is the face she saw as she came rushing back into her body.  That face belongs to David Mayer, a brainy outcast who dislikes Cara even more than she does him.
As Cara sorts through the ramifications of her near-death experience, and struggles to overcome her fear of telling everyone what really happened, she discovers a path she never realized lay ahead of her.
And as Cara is about to learn, there are no coincidences.
