Wish of Dragons by Aja James

Every lore of every clan, across time and space, dreamed of dragons. Did you ever wonder why?
Erebu and Sorin fought through countless lifetimes of trials and tribulations to find one another again. They even conquered death.
But Ere’s rebirth requires a price: he must answer the Celestial Summons when it comes and faithfully complete each task the Jade Emperor sets before him.
On the bright side, he doesn’t have to perform miracles alone. Sorin will be right there with him. One the not so bright side, his Fate, the Fate of all dragon Kind, and by extension, the Universal Balance, depend on the successful execution of each quest.
No pressure.
His third task is find and retrieve the Wish of Wonders.
