The River Rising

Zeta's quest to locate Dr. Selig leads him to another member of the infiltration unit design team, Dr. Myrell. He runs a non-profit organization called the Myrell center, where he constructs and tests new technology to help the handicapped. One of these is a young man named Kevin, who is confined to a wheelchair. The doctor has created a backpack device called a ""synaptic amplifier," which allows him to walk normally. Zeta and Ro sneak into the center disguised as Kevin and his backpack, but end up encountering a thief there to steal the real amplifier pack. On a non-handicapped person the pack provides them with fantastic strength and agility. Blake, the thief, escapes, but a security guard who had seen the Zeta/Ro illusion of Kevin there after-hours accuses him of the theft, and he is arrested for it. It's up to Zeta and Ro to find Blake and clear the innocent Kevin.
