The Superhero's Strike. Lightning Bolt, #4

After preventing a plane crash, Kevin Jason (Bolt) teams up with Strike, a fellow superhero, to find Strike's girlfriend, who mysteriously disappeared one day withouta trace. Their search leads them into the maze of a mad scientist, whose terrifying scientific monstrosities lurk around every corner. Far more terrifying than monsters, however, is the return of a long-dead supervillain, whose murky agenda may be far more dangerous than even the deadliest beast.
Even with the unexpected help of an old ally, Bolt may not be able to survive the maze, much less save Strike's girlfriend, or deal with the deadly secrets awaitinghim within.
