Sage Alexander and the Castle of Lost Souls

Third in the "epic journey of a reluctant hero who will try to thwart the Seven Princes of Hell"—the series that's the basis for the TigerBeat TV show (VOYA).
When an Indiana orphan makes a telepathic connection with Sage Alexander's great-grandfather, Arthur, whose soul has been missing for more than 150 years, it gets the attention of the Angelic Response Council. Rescuing Arthur Alexander's soul, which is trapped within a dragonhead of Remus, a mythical Typhon who resides within the Prince of Envy's Dark Realm castle, will be a deadly task. Compounding the problem is Sage's mentally unstable uncle, who lives life on the edge of darkness. When Sage's team of battle-hardened warriors wage war to reunite Arthur's body and soul, the fury of a legendary beast makes their escape a near impossibility.
