Siege and Sacrifice
From the Wall Street Journal bestselling author of The Paper Magician Series comes the enthralling climax of a cataclysmic war between monstrous creatures.
Sandis has finally freed herself from her master and his plans to use her as a vessel for the ancient beast Kolosos. But her master has found a new, impossible vessel: Sandis’s brother, Anon — a brother she long thought dead.
Kolosos is ancient, massive, and seemingly unbeatable. Fortunately, Sandis has her own monster — an ethereal fire horse that she can summon at will. In addition, she and Rone may have discovered the secret to defeating Kolosos: ancient lore that details the creation of magic. It could be the key to victory and the key to saving Anon.
The price is steep, and Sandis is willing to pay it. Rone is not, and his attempt to save her only pulls them apart. As both are tested in ways they never expected, Sandis and Rone will need to determine the sacrifices they are willing to make. If their efforts are not enough, their city will fall... just as the ancient city beneath it already has.

Charlie N. Holmberg
Charlie N. Holmberg has a knack for finding magic in the margins—the kind of wonder tucked inside ordinary things, like folded paper, whispered spells, or the quiet ache of a lonely heart. Best known for The Paper Magician series, she writes fantasy that doesn’t shout but hums—spellbinding stories where imaginative worlds meet deeply human characters, and the line between enchantment and reality is deliciously thin.
Raised in Salt Lake City and shaped by the worlds of anime and Star Trek, Holmberg’s early love for storytelling bloomed in fan fiction before evolving into fully realized novels. Her writing often carries that same sense of earnest imagination—worlds that are clever and surprising without ever losing their emotional grounding. Whether it’s the steampunk whimsy of The Plastic Magician, the eerie elegance of The Fifth Doll, or the slow-burning celestial magic of Star Mother, her books unfold with the quiet confidence of an author who trusts her readers to follow her into the strange and the beautiful.
