The Madness - J. Michael Straczynski

In The Madness, Sarah Ross has been using her power as a thief, stealing from the rich and... well, keeping it. Until the day she stole from the wrong person, a highly placed official who pressures the government to assassinate her. The plot, aided by socalled 'good' superheroes sponsored by the government, misses her but wipes out her family. Driven mad by grief, and laserfocused on revenge for the murder of her family, Sarah and a hidden side of her personality - an imaginary friend who may be more real than she believes - goes after these superpowered operatives determined to take her revenge, at any cost.
