If your curiosity needs whetting, check out the first two novels of a series I am writing.

It's called "Arc of The Immortals". The first novel is "Pursuit" (Chapter 1: Blood Debt), and the second is "Time Rifts". Time Rifts - Contents has background stories about the higher vibrational world of the Antarians. I recommend starting with "Pursuit", where Jac and Touzdae are introduced (two Antarian humanoids), for full immersion into the adventure.

I'm currently doing a massive re-write of book three "Ennead Immortals".
