Mortal Heart is the third book in the His Fair Assassin trilogy. [Grave Mercy and Dark Triumph are books one and two.] I really enjoyed Grave Mercy, and Dark Triumph was simply okay, BUT neither of them hold a candle to Mortal Heart, the story of Annith! I could barely put this book down, and when I was forced to, it was all I could think about!
Annith was the novitiate waiting at the convent as she watched her friends Ismae and Sybella sent out to do Mortain’s (Death) work. Annith mastered every assassin’s tool and was still not chosen for an assignment until one day the Abbess selects her to be the next Seeress — a job that would confine Annith to a room of isolation never to leave the convent. Annith does not feel suited to this position and is insulted that her superior assassin skills will not be used as a Handmaiden of Death. In order to find answers, she runs away from the convent only to immediately encounter Mortain’s Hellequin army and fall under the protection of the head Hellequin, Balthazaar.
Once Annith reaches the palace, she is able to serve the Duchess as she has long desired. The Duchess must make some difficult decisions to save her beloved country, but never fear…true love prevails!
This fantasy assassin series is highly recommended for 9th grade and up.
