FORGED UNITY: The Mirror Kingdoms - Book Four

by Susan Faw

An uneasy occupation hampered by sabotage. A resistance leader hell bent on revenge. And a family learns that peace is harder than war.

Two years after the brutal Northern War claimed Queen Isabela's life, Queen Liora and King Callum face an impossible maintain their occupation of Cindergarde or risk the alliance they sacrificed everything to build.

But Steinar Ironhand refuses to accept surrender. Leading the Cinder Brotherhood from the shadows, he wages a guerrilla campaign that kills soldiers and shatters the fragile peace. As Alliance forces debate withdrawal, Steinar discovers something that could change everything—a ritual to siphon power from an ancient prison. He doesn't realize he's cracking the very seal that keeps the Shadow King contained.

Meanwhile, Liora and Callum struggle to help their young children heal from a grandmother's death they barely understand. Six-year-old Finn has stopped speaking. Morgana's grief manifests as destructive outbursts. And empathic Kaela drowns in everyone's sadness, unable to shield herself from the weight of six kingdoms' pain.

As Steinar's ritual threatens catastrophe, unlikely allies must infiltrate the Forge-Heart before the Shadow King breaks free. But true peace demands more than stopping a ritual—it requires the hardest choice of trusting former enemies to become equal partners.

The Alliance was forged in war. Now it must be tempered in peace.

Queen Liora and King Callum are doing their best to safeguard the alliance they had forged through so much sacrifice, however serving two kingdoms was difficult and made demands on them which forced them apart. With distance their bond weakened, and with each weakness the seal keeping the demon below ground, weakened too. In this book we see Azareth insidioulsy reaching out towards the monarch's triplets, who are just three years old. He ignores Finn, but tempts Morgana, as well as Kaela. The children are all different, and their powers are too, and he is patient enough to study them and lure them to his traps. Meantime the alliance is being threatened and destabilised by those who stood to loose from a peace treaty. Lord Cassian is setting plots against plots and seems to have no conscience to mention. However he did not forsee how the heads of the four kingdoms in the alliance worked so well together to unravel a dire plot before it dismantled all their hard work. This books is amazing in its scope, the planning is intricate, as is the politics behind the plot which really endangers one of the royal siblings. I love how the alliance rally around one another and put the children's well being first. But the darkness below is patient and working stealthily to once again break his seal. Will he be able to manipulate Finn, Morgana and Kaela or will he put a wedge in their unity?
