Charmed Books 17-20

Paige Matthews is new to the whole "Power of Three" thing, and looking to explore her powers. So when she reads of a Wiccan convention taking place just outside of Las Vegas, she thinks it's a great opportunity for her and for her sisters to learn more about their witchy ways. Though the girls are all over saving innocents, they aren't that heavy into Wicca practices, and Paige thinks the retreat could be enlightening. 

Piper and Phoebe, however, aren't so sure. They're certain that while they spend their days battling honest-to-badness black magic, their so-called supernatural sisters will be nothing more than a bunch of blessed wanna-bes. Soon though, they hear of a rash of murders committed against practicing Wiccans, and making an appearance at the convention becomes top priority. But as they head for the desert campgrounds, are the Charmed Ones headed straight for disaster?

Paige is accustomed to the requirements of her job as a social worker, and she's willing to endure substandard pay, long hours, and emotional drain. After all, she wants to make a difference -- sometimes in a non-Charmed capacity. But she is unprepared for the anger and rage she encounters in Todd Corman, a young boy who has been bounced from caregiver to caregiver for so long that he doesn't trust authority. Still, Paige is sympathetic and determined to break through.

But when Phoebe stops by the agency for a quick hello, she is rocked by a vision that involves Todd. Strangely, the vision is shrouded in fog. After some investigation, Leo explains that this particular mist has nothing to do with the weather, but rather suggests that Todd's fate may not be set in stone. Todd has been targeted, and if the Charmed Ones are going to reverse destiny, they're going to have to race against the clock!

Phoebe Halliwell is stunned when her latest vision involves her younger half sister, Paige. The vision reveals to her that Paige is actually an imposter who will infiltrate the Power of Three and break it apart. However, Piper is dismissive when she learns of Phoebe's concerns -- so much so that Cole and Leo end up taking sides as well. Before long, all involved are on edge.

Paige senses that her sisters are acting strangely around her, so when she meets Timothy McBride, an attractive young stranger who purports to be a witch, she decides not to tell them. She wants to have something of her own, separate from her Charmed duties. Secrets are estranging the sisters from one another, and the timing isn't good. Women are turning up all over the city, dead by supernatural causes. The perpetrator may be connected to the sisters' past -- but if they can't work together, they might not be able to stop him.

The sisters are no strangers to Halloween hijinks. But this year, the Wiccan celebration of Samhain is met with a rash of destruction throughout the city. Upon further investigation, the Charmed Ones learn that the demolished buildings they've heard about are actually melting. These sites are in fact the location of dimensional portals, and they're under attack.

Piper, Phoebe, and Paige will need to secure these barriers in order to prevent all havoc from being released. But the demon working against them is no ordinary monster; it's a wraith, the product of a grief-stricken young witch seeking to resurrect her lost love. And hell hath no fury like a woman scorned....
