Catwoman, Vol. 2 #0 (1994)

Cat Shadows
Catwoman remembers part of her past; a mother who committed suicide and a father who crawled into a bottle and died there. A runaway, she was soon caught and sent to Seagate, a reform school. The place is run like a gulag, and soon enough keeping her ears open grants Selina a chance to escape. But she is caught again, and returned. The director assigns her various chores as punishment, and eventually discovers evidence the director has been falsifying reports and embezzling. A confrontation nearly gets Selina killed (chloroformed and thrown into the ocean), but she escapes and returnes. She demands the director remove her name from the records in exchange for silence, and then leaves (freeing the other girls as she does). She becomes a thief and learns the trade. A turning point comes when she learns about Batman, which motivates her to create her own costume and persona, Catwoman. At first stealing from criminals, she's soon stealing from anyone. In the present, she plans a new heist: from a socialite whose will leaves her possessions to her cat. Selina steals jewels and cat both!
