A Dark Time - The Chronicle of the Final Light, #5

Heroes are tested in the darkest moments, and not all of them return to the light. Private Avery Shetty has survived captivity on the alien world of Ferekon, but the experience has forever changed him. The scars of loss will never heal, but it's what's going on inside of him that presents the greatest danger. Originally, he had worried that his commanders would suppress the information he had on the untrustworthy Anirii.
Now, being silenced is the least of his concerns. As Shetty fights for his life, the war for Ferekon sees a new twist, with the Anirii revealing their true nature and designs. With the diminished combined Kedraalian and League fleet at its most vulnerable, only the strong of will can bring humanity and its allies out of the darkness. The fifth book of this action-packed hybrid of military science fiction and sprawling space opera ratchets up the suspense.
