Defiance. Cascade Wars, #3

Defiance is the third book in an exciting military scifi series and there are cliff hangers!Commander Monroe barely survived betrayal from within-his own XO nearly ended him. Now, with trust shattered and tensions running high, he must hold his crew together as a ruthless and defiant enemy launches a devastating assault. The city on Federation-21 burns under relentless attack, its defenses pushed to the brink.
But the battlefield holds more than destruction-secrets emerge, and shocking twists threaten to upend everything Monroe thought he understood about the war. Beyond the front lines, a far more insidious conflict unfolds. A conspiracy tightens its grip on the Federation as the powerful Great Families are drawn into the chaos. Thoros, their formidable leader, faces a reckoning unlike anything in his long and ruthless career-an encroaching darkness more dangerous than even he imagined.
And then comes the truth. Monroe and his crew uncover the enemy's grand design: a bold, unthinkable plan to carve out a new dominion on the fringes of Federation space-one that could shatter the balance of power forever. Defiance is the explosive third installment in a pulse-pounding military sci-fi saga-where every victory comes at a cost, and every revelation cuts deeper than the last.
