Dragon Detective

Nickel might be a water elemental dragon, but even he has limits-and the sudden rain storms, hail, and snow in midsummer are way over the line. Luckily, he works for Dane's Supernatural Consulting firm and can use those resources to figure out who keeps mucking with the weather and get them to stop.

Soon Nickel realizes he isn't the only one searching for the weather worker: the enemy he has been hunting for ten years has finally reappeared, and it's a race to see who will reach the weather worker first. Nickel isn't certain he'll win, or even survive, the attempt, but he'll do whatever it takes to save the dragons.
Dragon Soldier

The aftermath of the last battle has left Nickel weak in bed and grounded for the next decade. Despite being in trouble, Nickel wants to return to the battle against the enemy as soon as he can, but thoughts of Platinum, the dragon helping to nurse him back to health, keep distracting him.

Platinum can't believe how much his life has changed. He went from being a lonely fugitive on the run to part of a family in only hours. The last few days have been his happiest, especially now that he's met Nickel. He knows it's only temporary, though. The enemy that kept him captive for most of his life isn't finished with him yet, but even Platinum and Nickel's combined powers might not be enough to save them all.
