description -
One great omnibus of three of Crichton's most popular adventures (Congo, Sphere, & Eaters of the Dead), with his trademark blend of breathtaking suspense & cutting-edge technology.  
 
From the legendary ruins of a lost city in the jungle, to the mysterious depths of the ocean floor in the South Pacific, to the historic horrors of mortal combat in the tenth century A.D.--these fabulous stories transform fears of the unknown into moments of believable adventure and unbearable suspense.
