Twilight's Strength

Daniel:
The Night Realm is firmly in my Father's clutches, and Zyanna throws herself into every attack my father sends. But when Zyanna is injured, I ask King Phoenix for help. He comes. His forces are greater than ours, with magic and fighting skills beyond the Loyalists. He thinks we're incompetent, and I'm not the right husband for his sister. How can I protect Zyanna, prove my brother-in-law wrong, and save the kingdom? Zoe:
I came on this mission to the Night Realm for one reason: to prove that my life is fine, just the way it is. After an attack from King Edmund, I'm asked to lead a unit of soldiers to the Northern Wastelands in search of the Night Realm deity, Nosh Dem. But I'm not sure the life of a warrior is for me. Commander Adothlin would like me fighting at his side. And Nix? We were friends once. But now he's holding my hand one minute and asking royal favors the next. Nix:
My sister needs help, so I assemble the Twilight Realm soldiers and guards. There's one particular warrior I want on this trip: Zoe, who agrees to come. When we reach the Night Realm, nothing is easy. My sister is no longer a child. Daniel is more interested in protecting her than his kingdom. And Zoe is always surrounded by soldiers. Am I doomed to a millennium of solitude? Can I help Zyanna and Daniel save the Night Realm? And how can I win Zoe's heart? Zyanna:
I've learned to control my power and protect the Loyalists against attacks from King Edmund. When a stray knife sinks into my thigh, Daniel finally agrees that Yarissa can train me with weapons, but only for defensive purposes.
When my brother arrives, he's unimpressed with my husband and disappointed in me. The one thing Nix and Daniel do agree on is keeping me hidden-locked up-in the safe tree. But when a mysterious Twilight Realm warrior asks me to join her on a mission to the Northern Wastelands, I jump at the opportunity to prove I can fight for the Night Realm. Daniel and Nix refuse to let me go, but the choice isn't theirs. Twilight's Strength is the fourth and final book in the Twilight Realm Series. If you like strong female leads who help princes save their kingdoms, if you are a fan of sweet, clean romance, and if you like strong world-building, elves, magic, swordplay, and little dragons, this book is for you.
