Should i read the second Titan book before reading the third one?
It's not essential. Since the first two books were basically wrapping up loose ends from Nemesis
and The Sundered
, that made Orion's Hounds
the first book where they were on their proper mission, so I approached it as a "second pilot" of sorts, a fresh start. It does draw on some things from earlier books and episodes, but anything relevant, as always, is explained in the book itself.
