Secrets of the sky

"Kiya and Kinjal have succeeded in their first quest in the magical world of the Kingdom Beyond, but whatever good they achieved might not be enough. Their faithful flying horses Snowy and Raat reappear and whisk them back to the Kingdom to help the . . . winged merpeople who are slowly being poisoned by the very water in which they live. It is up to the twins to figure it out and put a stop to it. Fortunately, Kiya has the know-how to solve this mystery . . . if only she can put the pieces together before the evil serpent king Sesha knows they've reentered the Kingdom!"--Amazon.

"Twins Kiya and Kinjal must help the flying horses with a sudden invasion of their lands. It turns out that the tree ghosts are losing their forest! To save the trees, and the Kingdom, they must use their collective knowledge of this world and of course their magic!"--Amazon.

Kinjal and Kiya's dog disappears before their eyes. Then two enormous flying horses appear and insist on taking them to a place they have never heard of: the Sky Kingdom. The horses need their help solving a mystery: why the bees are disappearing, along with the nectar the horses need to survive. The twins must use Kiya's scientific skills and Kinjal's love of books and language to help the horses. Once there, they discover that the disappearance of the bees is more nefarious than they thought.
