Facebook Phantom, a new YA book published by Duckbill Books, has surprises to offer in the first few pages itself — there’s none of that grating teenage lingo some YA authors love to pass off as an exercise of getting into the skin of their characters. Seventeen-year-old Suzanne Sangi’s writing is lucid, crisp and plunges into what she does best - defining believable characters and setting the stage for darkness and doom to take over their lives.
