Transformers Dragon AU: Book 1 A Dragon Hunt [old]

Jack, Raf, and Miko were once normal people, but after spearing three dragons, their lives change quickly. They became Dragon - Shifters. A power almost forgotten by humans. But Dragons know it by heart. They now live on an island where they have everything they need. But when the time came for them to return to their old home, things become complicated. Vince becomes hungry for the power of Dragon - Shifting and vanishes. Jake, their father, is begging them to tell the clan where they now live. They are now faced with a choice: Tell them where they live and go look for Vince. Risking the safety of the dragons. Or not tell them and only have them make litters and have messenger dragons bring them and go look ... for Vince.
