Helium3: Omnibus Edition

Today, at the centre of our galaxy, dwell small colonies of a most extraordinary species – humans. Fourteen-year-old Mervyn Bright has courage, tenacity, and three close friends from the Space Academy: Loren, a brilliant but despised out-worlder, Tarun, heir to a once-powerful dynasty, & Aurora, niece to the embattled Patriarch. Together they make a formidable team.

Books 3.0, 3.1 & 3.2 together.
