Out There: Book Three: TiWat

After the narrowest of escapes from Adonae, Sami and Alejandro land on TiWat, the home planet of their relentless enemy, KetaNim.
TiWat is a bizarre and danger-filled world of forests and rivers. From the moment they arrive, Sami and Alejandro are running for their lives from the cruel ruler of the Southern TakTi, SimSimKeta. Keeping a half step ahead of fanged creatures, carnivorous plants, and dart-wielding warring clans, the two friends eventually hide out in yet another world, this one buried deep inside the mountains of TiWat.
In this strange world of endless caverns they discover the odd and beautiful society of the Svaash... and Sami’s father. He is alive, but apparently brain dead. Her father is the key to SimSimKeta's secret, that the TakTi have stolen the technology of the Adonae and intend to invade Earth.
Sami and Alejandro must escape TiWat. And not only to save themselves and Sami’s father. Now they must also warn humanity that SimSimKeta and the TakTi will soon be on their way to colonize Earth.
