Jayden Blue and The Wait of the Sun. A World So Close, #6

In this final book of the series, Jayden Blue and Raylene Hawkins know that they have learned from their harrowing experiences in the Forest of Night Fallen, and they're ready to journey again to the mountain of Val ka'Yoom. They don't know exactly how they'll help with the conflict between all of the iron lions and the Val, but they know that it's time to try again. Through every twist and turn of their adventure, everyone tells them that they must hurry-no time to wait! And no one can tell them exactly why.
When they're finally returning to the Lair of the Iron Lions, after having completed their mission, they want only two things: to get Hex and Halo back and to return home. Standing on the trail that winds through the wildflower fields, they all see the sun setting and feel that world growing cold. Jayden and Raylene are told by the iron lions that they can return someday-they'll know when. That sun, the giant cats say, will wait for them in A World So Close.
