Shades of night - Jackie Kessler

When Jet and Iridium - best friends turned enemies - came together to bring down a supervillain, they inadvertently destroyed the secret Corp-Co transmitter, whose frequency kept the New Chicago's heroes of in-line - and sane. Now the city is plunged into chaos as these heroes are suddenly the biggest threat. Corp-Co brings in a new Squadron from India - but when heroes are tied into a system of sponsorship, only money, and not a sense of duty, can persuade them to save the day.

As they haggle, Everyman sets out to destroy the powers with a group of enhanced super-soldiers, and the mysterious villain Doctor Hypnotic is lulling heroes and supervillains alike into his seductive web - a dream-world where everything is perfect, but nothing is real. Once again Jet and Iridium are forced to set aside their hatred of each other to do what they were born to do: save the world.
