Nine

The fourth BTLG book was such a thrilling ride! I was on the edge of my seat as the conspiracy surrounding EE-297 was finally unraveled. Kailoon's acquisition of the T-Mailer was a game-changer, and it was exciting to see the UEM take on the Aurigan Empire head on. The secret behind the gates was also uncovered, adding even more layers to the story. And now we finally know the true origin of the mysterious Nine - it only added to the intrigue of the book. I couldn't put it down and can't wait to see where the series goes next.
