An approachable introduction to elementary sheaf theory and its applications beyond pure math. Sheaves are mathematical constructions concerned with passages from local properties to global ones. They have played a fundamental role in the development of many areas of modern mathematics, yet the broad conceptual power of sheaf theory and its wide applicability to areas beyond pure math have only recently begun to be appreciated. Taking an applied category theory perspective, Sheaf Theory through Examples provides an approachable introduction to elementary sheaf theory and examines applications including n-colorings of graphs, satellite data, chess problems, Bayesian networks, self-similar groups, musical performance, complexes, and much more. With an emphasis on developing the theory via a wealth of well-motivated and vividly illustrated examples, Sheaf Theory through Examples supplements the formal development of concepts with philosophical reflections on topology, category theory, and sheaf theory, alongside a selection of advanced topics and examples that illustrate ideas like cellular sheaf cohomology, toposes, and geometric morphisms. Sheaf Theory through Examples seeks to bridge the powerful results of sheaf theory as used by mathematicians and real-world applications, while also supplementing the technical matters with a unique philosophical perspective attuned to the broader development of ideas.

A dark, epic fantasy about a girl who must rethink everything she believes after she is betrayed and hunted by the religion that raised her—from Megan Bannen, author of The Bird and the Blade. Perfect for fans of The Winner’s Curse and The Girl of Fire and Thorns. Gelya is a Vessel, a girl who channels the word of the One True God through song. Cloistered with the other Vessels of her faith, she believes—as all Ovinists do—that a saint imprisoned Elath the Great Demon centuries ago, saving humanity from earthly temptation. When Gelya stumbles into a deadly cover-up by the Ovinists’ military, she reluctantly teams up with Tavik, an enemy soldier, to survive. Tavik believes that Elath is actually a mother goddess who must be set free, but while he succeeds in opening Her prison, he inadvertently turns Gelya into Elath’s unwilling human vessel. Now the church that raised Gelya considers her a threat. In a race against the clock, she and Tavik must find a way to exorcise Elath’s presence from her body. But will this release stop the countdown to the end of the world, or will it be the cause of the earth’s destruction? And as Tavik and Gelya grow closer, another question lingers between them: What will become of Gelya?

"Edgewood has everything I love in a Kristen Ciccarelli book: lyrical prose, a romance that will hurt, and themes rooted in raw and intimate questions, making for a timeless tale." - Joan He, New York Times bestselling author of The Ones We're Meant to Find Can love survive the dark? No matter how far she runs, the forest of Edgewood always comes for Emeline Lark. The scent of damp earth curls into her nose when she sings and moss creeps across the stage. It’s as if the woods of her childhood, shrouded in folklore and tall tales, are trying to reclaim her. But Emeline has no patience for silly superstitions. When her grandfather disappears, leaving only a mysterious orb in his wake, the stories Emeline has always scoffed at suddenly seem less foolish. She enters the forest she has spent years trying to escape, only to have Hawthorne Fell, a handsome and brooding tithe collector, try to dissuade her from searching. Refusing to be deterred, Emeline finds herself drawn to the court of the fabled Wood King himself. She makes a deal—her voice for her grandfather’s freedom. Little does she know, she’s stumbled into the middle of a curse much bigger than herself, one that threatens the existence of this eerie world she’s trapped in, along with the devastating boy who feels so familiar. With the help of Hawthorne—an enemy turned reluctant ally who she grows closer to each day—Emeline sets out to not only save her grandfather’s life, but to right past wrongs, and in the process, discover her true voice. Haunting and romantic, Kristen Ciccarelli's Edgewood is an exciting novel from a bold, unforgettable voice in fantasy. "Darkly gorgeous and moving, Edgewood is full of curses and fae magic that will capture your heart and wrap it in thorns before setting you free again, forever changed. I devoured Edgewood whole and couldn't put it down." - Evelyn Skye, New York Times bestselling author of The Crown's Game

A genre-defying debut, this queer historical YA centers a wild and reckless trio who fly in the face of small-town tradition—full of compassion, love, and determination to live the lives of their choosing. It’s 1904 on an island just west of Norway, and Asta Hedstrom doesn’t want to marry her odious betrothed, Nils. But her mother believes she should be grateful for the possibility of any domestic future, given her single-sided deafness, unconventional appearance, and even stranger notions. Asta would rather spend her life performing in the village theater with her fellow outcasts: her best friend Gunnar Fuglestad and his secret boyfriend, wealthy Erlend Fournier. But the situation takes a dire turn when Nils lashes out in jealousy—gravely injuring Gunnar. Shunning marriage for good, Asta moves with Gunnar and Erlend to their secluded cabin above town. With few ties left to their families, they have one shot at gaining enough kroner to secure their way of life: win the village’s annual horse race. Despite Gunnar’s increasing misgivings, Asta and Erlend intend to prove this unheard-of arrangement will succeed. Asta trains as a blacksmith; Erlend cares for recovering Gunnar. But as race day approaches, the villagers’ hateful ignorance only grows stronger. With this year’s competition proving dangerous for the trio, Asta and Erlend soon find they face another equally deadly peril: the possibility of losing Gunnar, and their found family, forever.
