Oracles of Delphi Keep

According to prophecy, a trip through the magical portal near the Dover, England, orphanage where Ian and Theo live will bring them to the third Oracle, a child with extraordinary healing powers to help defeat a great evil, but it will also lead to Ian's death.

In 1940, when Delphi Keep is taken over by the Royal Navy as a communications outpost, Ian, Theo, and Carl dread being evacuated to the Earl's winter residence where they will no longer be protected, but are even more concerned about deciphering the third prophecy and identifying the Secret Keeper.
