Virus

No one is safe.

A lethal virus has taken over Grant, Massachusetts. And no one knows where it comes from. The staff of Med Center is struggling to save lives and find answers for panicked families.

The volunteers are at the center of it all--but they've got troubles of their own.

Susannah: The daughter of the richest man in Grant just wants to work at the hospital. Her partying twin brother Sam's thoughts are elsewhere....

Will: One medical emergency call after another gives him little time for a romance he knows is hopeless.

Kate: Ambitious and smart, she is afraid her dreams will never come true.

Callie: The scheming daughter of the hospital administrator is determined to make trouble... for everyone.

The Med Center crew fights an enemy they can't see. But they feel the terror everywhere.
