Susan Percy - Anna's sister and formerly a drug and alcohol addict. Susan is similar in appearance to Anna except she bleaches her blonde hair to platinum and favors a more rebellious look. Susan is intelligent and studied at Bowdoin University until she fell in with the wrong crowd. Susan despises her father for paying off her ex-boyfriend into dumping her, in a misguided attempt to get Susan off drugs. Anna helps the two reconcile and Susan returns to rehab, this time at White Mountains in Arizona. When she finishes, she gets a job at the Kripalu institute. In her next appearance in the series, Susan is sober and much happier.
