Cyborg IV (4)is the last of the "Six Millin Dollar Man" books writen by Mr. Caidin and the last based purely on the characters in the first book. This book takes Steve back into space in the Asp, which is a space fighter, in which Steve is merged through connections with his bionic limbs. Fighting Russian space fighters for the control of the ultimate 'High Ground'. This is also the first time that Steve is able to see (in a sense) with his bionic eye. The story is the shortest of the the set, but also one of the most action packed. It a great read if you can get your hands on it.
