Brenawyn has made impossible promises.

She has agreed to become the Druid high priestess, she has agreed to restore the balance between worlds, she has promised to save Alexander from a century’s old curse, and to top it all off, the god Finvarra has just dropped her 600 years in past so that she can fulfill an ancient prophecy.

While Brenawyn struggles to save them, Maggie and Alexander fight battles of their own in different times and separate worlds. If Brenawyn fails in her promises, the world may never be the same.
