Warrior’s Soul: The Collective Book 4 (The Collective Series)

Five years ago, Saber Isles walked away from her mate. She didn’t have a choice. As a changeling tiger working for the Realm Defence Unit, she had spent years enforcing the oldest rule of her kind: humans stay in the dark while her people bled in the shadows—a rule that her kind had maintained for thousands of years.

That fragile secrecy shatters when a Demonic War erupts, and humans get a brutal awakening. For the first time, they fight shoulder to shoulder with creatures they never knew existed. Riddled with remorse for leaving her mate unprotected, Saber searches for him, but a foolish mistake leads to her capture. The enemy is determined to turn her rogue—to exploit the tiger’s power and cunning for their own ends.

Kayde has spent years trying—and failing—to forget the woman who vanished from his life without a trace. Battle-hardened and exhausted, he’s buried the hollow place she left behind under discipline, loyalty, and the day-to-day grind of war. But when his path finally crosses Saber’s again, it’s not the sharp-tongued, guarded woman he finds. It’s a wounded tiger who watches him with familiar eyes…with no way to tell him the truth.

Thrown together on a high-risk mission through nightmare realms and collapsing borders, Saber and Kayde must navigate hostile territory, political landmines, and a fiercely loyal found family who refuse to stand down. Old wounds reopen. Old sparks ignite.

To survive, they’ll have to trust the bond she’s spent five years denying—and accept that sometimes the only way to win a war is to stand shoulder to shoulder with the one person she can’t bear to lose.
