Stranger Inside (Daw Book Collectors)

From the author of The Omega Game...
There's something inside Jimmy-and it's burning to get out...

For five years, Nate Adriano has been on the most bizarre case he's ever encountered, a situation hidden by the government. Fifteen teenagers have died, seemingly from internally generated fires. But one teenager, Jimmy Somerset has all the symptoms, yet has defied the odds-and may hold the answer to what exactly is inside.
