Aenwyn Duldurn grew up knowing that practicing magic is punishable by death, no questions asked. But everything she knows changes when she receives information about her missing sister, Ansa, telling Aenwyn she has magical abilities inside herself and that a group of warlocks want to siphon the power to open a portal of time to find a book that will forever change the world Aenwyn lives in. This change will have dire consequences for everyone and everything Aenwyn knows. The only problem is that Aenwyn and her sister will have to combine their powers, possibly killing one or both of them. The only way for Aenwyn to save herself, her sister, and everything she loves is to trick the warlocks into combining their power with hers, but will it kill her or them?
