Dragon Series by Laurence Yep

Centuries of wandering have taught the exiled dragon princess Shimmer that humans are beneath her notice. But she allows young Thorn to join her in the search for the evil witch Civet--and the quest to restore her dragon clan's lost home.

Returning to her underwater dragon kingdom expecting to be rewarded for capturing an enchantress, Shimmer and young Thorn instead must continue their quest to restore the dragon princess’s clan to its ancestral home. A tale of dungeons, sea monsters, and magicians, this sequel to Dragon of the Lost Sea "will lure even more readers to [Yep's] legion of followers." —V. "The novel's fast pace [and] exciting action sequences mark this as a tale sure to delight fantasy lovers." —The ALAN Review.

Monkey tells the tale as he joins the dragon princess, Shimmer, and, along with two feisty humans, they embark on a mission to recover the dragon homeland. It has been Shimmer's personal quest for years, ever since Witch Civet stole the sea, and the dragons were evicted from their magnificent palaces of coral and pearl. Now the arch-enemy Civet is repentant, and she too has thrown in her lot with this fearless band.

The evil, immortal Boneless King has taken possession of the powerful dragon cauldron - with the soul of Thorn, the human child, trapped inside - and has declared all-out war on dragonkind. His plan: to use the cauldron to boil the seas and destroy the dragons. And he has convinced Shimmer's brother, Pomfret, to be his ally. The dragon princess Shimmer, the wizard Monkey, and Indigo, a human child, transform themselves into guards, horses, and even fleas to elude the despicable Boneless King... moreThe evil, immortal Boneless King has taken possession of the powerful dragon cauldron - with the soul of Thorn, the human child, trapped inside - and has declared all-out war on dragonkind.
