This is part two of the review of book one of the Forerunner saga. Continuing from where I left off, Bornstellar with his Humans find the Didact. He shows them old Precursor ruins. They are caught by Forerunners on the quarantined worlds of the San'Shyuum. This is where we see Halo, and meet the master builder. If you like books that explore science fiction, and play “Halo“ this is a good book that provides insight on the Forerunners.
