Saving Anakin (Book 2)

The second book to "Anakin's New Padawan" is "Saving Anakin".

If you haven't read the first book "Anakin's New Padawan" you will not understand this book at all.

Anakin has come out of his coma, but didn't come back totally himself.
Haunted by his vision, he is driven by an unseen for, to the dark side. Something happened is his coma so that he became
slightly consumed by darkness. Or so they think.
Even though the darkness is in him, he still has a choice of which side he is on. The Darkness only makes it harder to stay in the Light. Anakin has to use all his might to stay with the Light.
The only way to save Anakin is to cast out the Darkness.
But how? What is the Darkness? How do you cast out Darkness? Can Anakin be saved?

Found out what happens to the famous Anakin Skywalker in his battle for the Light.

P.s. I don't own Star Wars. Disney and Lucas Arts does.
