Soul of the Bride — Constance M. Burge

In a land of lost, wandering souls, Journey with care on the River Styx. A prince of darkness plays his roles -- Protect the Charmed Ones from his tricks. Prue's editor at 415 magazine offers her a challenge: if she takes a really fantastic photo, he'll run it on the cover. This could be Prue's big break -- if she can come up with a killer concept. But when Prue snaps the shutter, all the models collapse into a deathly slumber! To rescue the innocents, the Charmed Ones descend into Hades, fighting underworld perils and uncovering an unholy plot. To rescue the missing models, they must match wits with the greatest of the ancient Greek gods -- and one of the sisters might not be allowed to return to her mortal life.
