The Returned (Legends of the Space Marines)

On the world of Gathis, atop the Ghostmountain, sits the Eyrie, fortress-monastery of the Doom Eagles. Here they memorialise their honoured dead, then forget them. But what to do when one of those dead comes back to life? Brother Tarikus returns from years of captivity and must contend with suspicion and mistrust as he strives to reclaim his place in the Chapter. Read it because
Returning home to the Eyrie after years of captivity, Tarikus wants nothing more than to rejoin his Chapter. But suspicion and mistrust await him at every turn.
