Dead Head

Description for DEAD HEAD by Allen Wyler:

Brain Surgery or Murder?

When brain surgeon Russell Lawton is abducted at gunpoint by terrorists, he's sure there's a mistake: how could he be useful to them? To his horror, he learns they have kidnapped his only child, eight-year old Angela. Unless Russell does what they want, they will bury her alive.
To buy time Russell agrees, and is immediately confronted with a seemingly impossible surgical problem. He must develop an innovative computer that can manipulate a robot by using brain activity. And fast, or his daughter dies.
Why? When Russell finds out why the terrorists need the computer, and how they plan to use it on a human being, he can't believe they're serious. But the consequences for not taking them seriously are his daughter's life, and the lives of millions of innocent people.
