When sixteen-year-old Abigail's mother dies in Scotland--leaving a faded photo, a weirdly cryptic letter, and a one-way ticket to America--she feels nothing. Why should she? Her mother abandoned her as a baby to grow up on an anti-nuclear commune and then in ugly foster homes. But the letter is a surprise in more ways than one: Her father is living in California. What's more, she has an eighteen-year-old sister, Becky. And the two are expecting Abigail to move in with them.
 
While struggling to overcome her natural suspicions of a note from beyond the grave (not to mention anything positive) Abigail tries to fit in with her strange, new American family: a distant father with a closed past, a too-perfect stepmother, and most puzzling of all, her long-lost sister. Becky sweeps Abigail into a shadowy underground movement involving clandestine street art, jailbreaks, and a bizarre double life. Soon, Abigail uncovers something unimaginable: a plot with vast implications, one that is aimed not only at controlling her sister, but the behavior of rebellious teens across the globe.
