Titans of Chaos by John C. Wright
The five have made incredible discoveries about themselves. Amelia is apparently a fourth-dimensional being; Victor is a synthetic man who can control the molecular arrangement of matter; Vanity can find secret passageways through solid walls; Colin is a psychic; and Quentin is a warlock. Each power comes from a different paradigm or view of the universe. They have learned to control their strange abilities and have escaped into our world; now their true battle for survival begins.
