Supers Wear Spandex *third book to Heroes Wear Capes

Xander Mendez isn't sure he knows what's real anymore. Yesterday he was sure he was a superhero protecting Kingdom City along with friends, but now he was being told all of that was made up.
Xander isn't a superhero. He's a patient in a mental institution.
Everyone he thought he knew is someone else. His best friend is his short-tempered hatful roommate, the girl he loved who he saw die is his therapist, and his friend the vigilante badass is a lunatic stuck at the mental age of nine.
Nothing seems right. Maybe Xander really was a mental patient. Maybe he did make it all up.
Maybe he was crazy.
Meanwhile, in the world Xander thinks he made up, a heinous villain is trying to take over the city with a severely addictive drug, a vigilante is having second thoughts, a hero is keeping his love and nemesis captive, and an agent is coming to terms with his past. And the city's only hope may be a speedster stuck in a prison of their own creation.
