When Darkness Hunts the Dawn - Dragons of Rokahn, #1

Rebel. Captive. Dragon. Condemned for leading a rebellion against a petty tyrant, Mikoneh and his twin sister resign themselves to a fiery death. But when the stake is lit, the flames answer to Mikoneh-and he and his sister escape amid the ensuing chaos. On the run, they discover they're being chased by worse than the tyrant's knights. From deep underground, Dark Mages hunt them for a birthright they never knew.
With unexpected help from a magic box and a peculiar woodelf, the twins race for foreign lands to seek refuge from the legendary Dragon King. But their relentless pursuers will stop at nothing to use Mikoneh's blood to stir the embers of an ancient war against humans, elves, and dragons. Soar into the first book of a dragon-centric adventure rife with political intrigue, fierce duels, and deep lore set in a complex fantasy world!
