Dragon Detective (Supernatural Consultant #4) by Mell Eight
Nickel might be a water elemental dragon, but even he has limits—and the sudden rain storms, hail, and snow in mid-summer 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.
It doesn’t take long for Nickel to realize 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 which of them 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.
