In 2013, V.E. Schwab released five trading cards based on Vicious. Each trading card was based on a character from a book which included Eli, Victor, Serena and Sydney with an additional card based on V.E. Schwab. To order the trading cards you would have to buy the book (online or digitally), read it, review it and send a link with the review to email@example.com. Then she would send the trading cards to the reviewer.
