There are five episodes of her show "Lisa Williams: Voices from the Other Side" available on Lifetime. Possibly this is the show they are bringing back, however, it does not say anything about dates or times. The link to the show on Lifetime is: http://www.mylifetime.com/on-tv/shows/voices-other-side.
For anyone living in L.A., I also saw that she will be doing a book signing at The Bodhi Tree on Sunday, May 10, 2009. That's this weekend!
