Description:

Amy's encounter with dinosaurs and cave dwellers and aliens was pretty wild. Now her quest to stop the spread of the infectious bacteria gets even more bizarre as she agrees to take another perilous voyage.

A voyage inside a plague-ridden human body.

If Amy survives being injected into this complex landscape where good cells are waging battle against bad cells, she could save millions of lives. But it's a do-or-die world in there.
