Nica Ashley can hardly recognize her own life anymore. Since moving to Barrington, she's discovered that her father is a secret government agent, she's fallen for the hot, brooding Jackson Winters, and oh yeah, there's the whole "I can become invisible" thing that happens whenever one of those strange green pulses light up the sky.

But despite everything that's happened, nothing can prepare Nica for the sudden reappearance of Dana Fox, Jackson's girlfriend and the key to unraveling Bar Tech's sinister plot once and for all. Armed with just her invisibility and a lot of questions, Nica is determined to do just that...even if it means breaking curfew.
