Christian Bateleur faces his most formidable challenge yet as the Tainted War escalates to terrifying new heights. When a series of gruesome murders leads his team to London, Christian confronts Euryale-an ancient evil who has built an army unlike any the Bishops have faced before.

As the battle rages across the British countryside, Christian must dig deeper than ever to find strength he never knew existed. With his team fighting desperately against overwhelming odds, shocking revelations about his lineage force Christian to confront not just the enemy, but questions about his own destiny.

With his trademark wit intact but his resolve tested like never before, Christian's journey takes him to the very edge of darkness. If he fails, he won't just lose this battle-he'll risk losing everything he's sworn to protect.

In this gripping fourth installment of the Tainted War Series, W.J. Grupe Jr. delivers his most intense and personal battle yet, where the line between savior and destroyer has never been thinner.
