Cate's destined for unimaginable power. if she can survive ascension. Welcome to Excalibar, an elite team with Cate McCray at the helm. Cate's as tough as they come, and she's not about to let anyone mess with her fellow Magickind. That's why Excalibar is locked in a bitter battle with the Covenant; an ancient organization with one goal-enslaving Magickind. Cate's only going to let that happen over her dead body.
Which might be why the Covenant is intent on killing her; that or the prophecy that she'll destroy the Covenant. Surprise surprise, Cate's not too keen on dying. So long as she can gain immortality, everything will be fine. but that means surviving ascension. With her elemental partner, Jason Talbot, at her side, she's ready to take on every Covenant attack.
