Seventeen-year-old Misaki Ashford has two things left from the life she lost: a battered dagger etched with half-remembered sigils-and the unshakable certainty that her brilliant sister, Ryoko, isn't dead.When the wind itself starts whispering the same name, Misaki leaves the quiet farm where Eli raised her and heads for Berkshire, a fortress-city built on old scars and older magic. Its streets snarl with humans, dwarves, elves, and shadow-skinned Umbrosires; its towers hum with the Incar Mage Order; and its training horns call misfits to a yard where broken blades learn not to break again.There Misaki finds Topher Silverhand's private unit-Astrid the knife-dancing elf, Bacchus the laughing berserker, Brelki who slips through stone and silence, Shamgar with a journal full of angles, Tess with soot-smeared goggles and ideas that spark-and discovers two hard truths: she's not the only one hunting Ryoko's trail, and the thing burning in Misaki's blood doesn't behave like any spell this city knows.Topher's Misfits swear to keep Misaki alive long enough to learn control. The Order wants to weigh her worth against the city's safety. Rivals, zealots, and things with too many teeth want the power she can't yet name. And all the while, a patient phoenix waits in Misaki's dreams-not flying, not fleeing, just watching.To find her sister, Misaki must thread a city of secrets, outthink an institution that molds mages into weapons, and decide which truth is hers: the legacy the Order insists she inherit, or the family she chooses in a unit that refuses to quit. If she can't master the storm inside her, Berkshire will burn. If she can... the world might change its mind about what's possible.Echoes of Horns & Sigils launches a twelve-book epic of found family, ancient wars, and time-scarred magic-where horn calls still shiver in the stone, sigils remember who wrote them, and one girl learns that rewriting a spell is easy compared to rewriting who you are.
