From publisher blurb:

As a child survivor of a terrible disaster, Hannah was pulled from the wreckage by a super powered hero. Although she found herself in a caring foster home she became obsessed with heroes and super powered beings, dreaming of becoming one, herself. Her education took her into in-depth studies of the super human phenomenon and their nature and, eventually, landed her work as a leading consultant to the government on super powered beings and their capabilities. Exposure to an unusual orb during an investigation granted her the ability to surround herself with a protexctive aura and move at supersonic speed. Her childhood dream come true, she has taken to the streets as REDLINE!
