Books in the Veil Walker series

It's hard enough being a seventeen year old Veil Walker, but when your boyfriend's a demigod and your mom's dating a soul sucker, things can get a lot worse. Pandora has seen ghosts since she was a kid, and now she learns she can bring back the spirits of the dead. Why would she do that? She has enough trouble getting rid of the ones stuck on this side. One annoyingly perky ghost wants Pandora to find her killer, but Ukwa, her super-hot boyfriend, doesn't like the idea. When trouble finds her, will she discover the true strength of a Veil Walker or, like the others, will her soul be trapped in her own Pandora's Jar forever?
