The Keepers. Covert Moon, #4

When war reaches its end, no heart escapes unbroken. Marigold Blaine has endured betrayal, captivity, and prophecy-but nothing could prepare her for the fight to reclaim her stolen child. With the fate of Beatrice bound to ancient magic, Marigold must face the one enemy she never thought she'd confront: her own blood. Eamonn, Captain of the Watchers, stands at the edge of love and loyalty as the final war ignites.
With realms on the brink and old powers awakening, he must lead where kings cannot, and fight for a future that may cost him everything. As prophecy meets its end and the last battle threatens all realms, Marigold and Eamonn must face the truth: some victories are bought with more than blood. Forged in love. Tested by blood. Sealed by fate. The Keepers is the fourth and final book in the complete Covert Moon series featuring witches, shifters, fae, betrayals, battles, and a love strong enough to defy destiny. If you like Fated Mates, Cross-Realm Romance, Enemies to Lovers, Forced Proximity, Coming Into Power, Found Family, Witch Romance, Shifter Romance, Portal Fantasy, you know what to do!
