Doomsday is the epic conclusion in the bestselling Phoenix Files series. After ninety-nine days of lock down, the end of the world is right on schedule.

With less than a day to go until the end of the world, there's nowhere left to hide. In a few short hours, the world's population will be wiped out, and Phoenix alone will rise from the ashes.

Shackleton's security guards are moments away from discovering Luke and Jordan's families. Peter, violent and uncontrollable, is on the loose. And war is still raging in town.

Luke and Jordan don't think they'll make it through the night, let alone save the day. But just when things seem hopeless, an offer of help arrives from the last place anyone could have expected. Can it be trusted, or is this the final piece in Shackleton's deadly plan?

Whatever happens next, the world as they know it is coming to an end.
