Gifting a Dragon's Heart

When he learns his father is dying, Roan leaves the wilds to return to the home he ran away from ten years prior. Roan knows the inevitable family reunion will be difficult, but then he meets Lyss, his former beau, who is the reason he had to leave. Roan doesn't know what to feel or how to react to this older version of Lyss, but before he can get his emotions in order, a letter comes from the untamed wilds region telling him the town he's called home for the last ten years is under attack.
Traveling back to the wilds accompanied by Lyss ought to give Roan time to figure out his feelings. However, the army, wyverns, and dragons all make finding time to even speak with Lyss difficult. Besides, ten years is a long time. When the battle is over, Roan and Lyss have their own separate lives to return to, assuming they both survive the fight to come.
