Battle: The Wizard and The Warrior Book Three (Paperback) (ISBN-13: 9780648218159)

After the decimation and the fall,
When the new power rises
And the Wizard and Warrior meet,
Old and new blood will combine
With the two who are not what they seem.
The key is the Ember Casket, to trap and calm the chaos,
Or send it beyond to save one and all.

Aliah and Seamus won their first encounter with the god trying to take over their home, so you would think they would be confident in their ability to banish their foe from Aria's shores once and for all.

Instead Aliah channels all her energies into becoming the best warrior she can be, and Seamus wonders why they are even bothering given they are doomed to fail: he even goes as far as to call their group "mice nibbling at the feet of a giant."

With a spy in their midst, the defence of Hand to organise, not to mention a mountain of scrolls to read through, can the Wizard and the Warrior free Aria from the greatest threat it has ever faced?
