Computer security expert and reformed hacker Diana Highsmith
has not ventured beyond her home for more than a year—not
since that fateful climbing vacation in Switzerland took
Daniel's life. Haunted by the sound of Daniel's cries
echoing across the gorge as he fell, Diana cannot stop
thinking about the life they'll never have—grief that has
transformed her into a recluse.
Diana doesn't have to
shut herself off completely from the world, though; she and
Daniel's best friend run a thriving Internet security
company. From her home, in her pajamas, Diana assesses
security breaches, both potential and real, and offers
clients a way to protect themselves from hackers—the kind of
disruptions Diana herself used to create. Once Diana has a
game plan she is able to meet with clients in OtherWorld, an
Internet-based platform, using Nadia, an avatar she created
for herself. Diana knows she'll have to rejoin the "real
world" eventually, but right now a few steps from her door
each morning is all she can handle.
When Diana's
sister goes missing, however, she is forced to do the
impossible: brave both the outside world and her own
personal demons to find her sister. As one step outside
leads to another, Diana soon discovers that she is following
a trail fraught with danger—and uncovering a web of deceit
and betrayal, both online and real-life, that threatens not
only her sister's life, but her own.
