«The Treasured One» by David Eddings, Leigh Eddings

The second brilliant book in the fantasy series set in an entirely new world from bestselling authors David and Leigh Eddings.
They are called the Dreamers. They look like sleeping children. They are, in fact, Gods.
Despite the literally earth-shattering climax of The Elder Gods, Dahlaine still does not regret having brought the Dreamers into the world of the Elder Gods. He only wishes he’d thought harder about the consequences.
His sister Aracia fears the whole world will collapse in on itself if the Dreamers should all wake up and realize where they are. It’s bad enough with them dreaming the future, but at least it’s a future.
Dahlain is pretty sure he’s safe from an ‘I-told-you-so’ from Aracia. The Dreamers give the Elder Gods a chance in the battle against the vicious Ruler of the Wasteland.
Then spies of very short stature start cropping up in Veltan’s bucolic and peaceful domain.They look like people, or maybe they all look like the same person, but they are more sinister than that.
Fortunately, Dahlaine is soon on the scene riding his thunderbolt. This second story of the sibling Gods is the story of the first god Dahlaine and his child Yaltar, who is so dangerous when asleep. And it is the story of the Treasured One, a mysterious presence who is controlling Yaltar’s dreams!
