Mycah Dunleavy has two goals in life: to protect her friends and to defend the World Below. In order to take her fight to the enemy she must become the most powerful witch she can be. But that power comes at a price.

In fulfulling her first goal, she committed the cardinal sin of using her magic to harm others. And to attain the second, she must combine in a ritual with a Watchtower Knight … despite the fact she can't bear to be touched.

Unphased by Mycah's defensive armor, Sebastian wants to claim her as his own and he intends to woo her long and slow. Then Mycah comes up with a crazy plan to gain more power and he becomes nothing more than a means to an end—a role he has no intention of accepting without a fight.

But there are bigger threats to deal with in the World Between. Mycah's life is threatened, four Witches are kidnapped, and once again the enemy is knocking at the door. Time is running out, and if Sebastian and Mycah don't find a way to work together, both of their worlds could be lost.
