The Dragon Bond: Heirs of Lyra

Now that King Alan and Queen Ariana's three children are all grown up, it's time for them to make their own adventures. As King Alan continues his efforts to gain allies for the impending war ahead, Prince Henry must play his part as future king and prepare to one day take the throne.
Meanwhile, Prince Ralf and his dragon, Mirum, do their best to learn more about their bond and how to use their magic. It is crucial that he and Mirum be ready for war.
The last child, Elysia, is getting into her own share of trouble and trying to dodge her new and unwanted guardian, Shade. But without him, Elysia's beauty and rebellious ways will only get her in to trouble. And as she tries to make her father proud, she may wind up risking the safety of the entire kingdom.
