Master of Fate (Merlin's Legacy #3)

Davon Fredericks is on a self-appointed mission to keep Mad Alys sane. And that job’s never been harder.

Alys Hawkwood is the most powerful seer among the witches of the Magekind. She’s seen a lot of horrors in her visions, but this is the worst: the destruction of the Magekind. The only way to prevent the deaths of everyone she cares about is to allow their worst enemy to kidnap her. Her only hope of rescue is her vampire partner, Davon -- the man she loves -- and the one she can never have.

To carry out her plan and save them all, Davon must pull off the impossible: take on a dragon and countless alien enemies alone. But his most deadly opponent is Alys herself…
