A Guardian From Earth (Rediscovery, #2)

The stons were dead, but that left Grace alone to try to learn to control her new abilities. When a solution presents itself, she begins learning just how far there is to go on the new journey she started. A new family, a new home, and learning to adapt to a completely different environment.

But for greater challenges, she also discovers there are greater rewards - and the universe always has a greater challenge in store.
