StarCraft: The Dark Templar Saga #3: Twilight [EPUB ebook] 

After the seeming defeat of the dark archon Ulrezaj on the protoss homeworld of Aiur, Jake and Rosemary become separated as they flee through the newly repaired warp gate. Rosemary finds herself with the other refugee protoss on Shakuras, while Jake is catapulted elsewhere. But Jake does not have long to live: their enemies are regrouping, and Zamara’s essence must be separated from Jake’s mind before time runs out.
