Query: A top notch read!

A roller-coaster ride through an astonishing world. Jerry Jay Carroll effortlessly plants you in the middle of a breathtaking adventure -- completely implausible and yet thoroughly believable and engaging, thanks to his gifted writing. It reminded me of the opening moments of the film "The Fugitive" - you begin on the edge of your seat and never get off it through the rest of the book. Michael Crighton's (later) book TIMELINE borrows much of Carroll's theme: an unexpected trip to another era, where brutal reality is confronted and life and death decisions are commonplace. Couldn't put this one down. His sequel DOG EAT DOG is even better. INHUMAN BEINGS, while written in an entirely different genre, is also outstanding. I say, order everything Carroll's written and take them all on vacation with you. You won't be sorrow.
