Red Sky in Mourning: The Dragon Rider Chronicles, Book Three (Paperback) (ISBN-13: 9798987697276)

Time is running out.

Darkness shrouds Balphrahn. An undead army swarms the land, hunting the dragons and killing all who stand in their way, at the bidding of a necromancer who should be long dead. The invasion devastates the land. Briant and Aithne race against time to master their powerful and untested magic before their allies fall. When the enemy captures Wybren Tanwen, the dragon riders' leader, they must strike to defeat the ancient evil before Balphrahn is lost forever.

But sometimes, when you think the fight is over, it's only begun.
