After making early gains on the battlefields, General Washington’s struggling young armies are being relentlessly pressed back by British troops and Hessian mercenaries. Among the enemy’s ranks is a mysterious force from the Covenant, a secret society of evil witches that for centuries has been pulling the strings of European history: a Hessian necromancer who drinks the power of other witches like a vampire and whose allies include devils and ghosts. Now this man seeks to sap the fighting spirit of Washington’s troops by means of a pernicious curse, chaining the souls of the dead to the spirits of the living.

Against him stand Proctor Brown and Deborah Walcott, two young patriots who lead a ragtag band of witches as much in danger from their own side as from the enemy. Proctor and Deborah must find a way to break the Hessian’s curse before the newborn revolution is smothered in its cradle—and the Covenant extends its dark dominion to the shores of America, extinguishing forever the already sputtering torch of liberty.
