In the final chapter of the Cage Series, Wyatt must lay everything on the line as he attempts to save not only Jess and Natalie but also prevent a war between angels and demons. The only way to thwart this travesty is to find the Key of Light. In Maddock's hands the Key will allow him to open a gateway straight into the heart of Heaven and release the full power of Hell's might...revenge for their fall from grace. However, when Wyatt is told his daughter is to be the sacrificial lamb to be slain by none other than her mother to bring forth the one to lead Hell's army in the fight, Maddock's son, he leads the charge to find his family. A warning comes from an old friend not to give into the power within. If he lets his angelic half consume him, he will no longer be allowed to remain on earth to live the life of peace for which he so desperately longs and will have no other choice but to return to Heaven a full-fledged angel. However, to defeat Maddock, Wyatt may have to make the ultimate sacrifice.
