Ancient powers. Strong love. Desperate times. 1883. Hanne would give anything to be free of the ancestral Viking curse that overcomes her when she or anyone she loves is in danger. She becomes a Berserker—an elegant, graceful and shameless killer. When she kills three men attacking their father, Hanne and her siblings must flee Norway and head to the American frontier, on a desperate search for their uncle, the one man who can help Hanne learn to control her powers. A gripping and emotional story filled with adventure, destruction, longing and redemption. \" Berserker is a triumph , introducing a wholly-new breed of Viking superhero. It's a completely winning, romantic, and heart-wrenching historical fantasy . Your pulse will race from page one of this rich, rugged adventure of a book.\" —Alyson Noël, New York Times -bestselling author of The Immortals series \"[Hanne's] internal struggle with her brutal nature as a berserker is intensely real and will resonate with readers who feel beset by forces outside of their control. A bloody and fast-paced genre mash-up.\" — Publishers Weekly","forthcoming":false,"isbn13":"9781250180766","publication_date":"20181016","publisher":"Square Fish","slug":"berserker","subtitle":"Kindle Edition","title":"Berserker"},"discovery":{"categories":{"all":[{"bisac_code":"FIC027180","confidence_band":"medium","label":"Viking Romance","score":0.7801,"source":"bisac_hint_model"},{"bisac_code":"YAF030010","confidence_band":"medium","label":"Arthurian YA","score":0.762,"source":"bisac_hint_model"},{"bisac_code":"YAF019040","confidence_band":"medium","label":"Historical YA Fantasy","score":0.7579,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC027180","confidence_band":"medium","label":"Viking Romance","score":0.7801,"source":"bisac_hint_model"},{"bisac_code":"YAF030010","confidence_band":"medium","label":"Arthurian YA","score":0.762,"source":"bisac_hint_model"},{"bisac_code":"YAF019040","confidence_band":"medium","label":"Historical YA Fantasy","score":0.7579,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"YAF024150","confidence_band":"high","label":"19th-Century US YA","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF030000","confidence_band":"high","label":"Myths & Legends for Teens","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF052030","confidence_band":"high","label":"Historical YA Romance","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Viking Romance","score":0.7801,"slug":"viking-romance"},{"label":"Arthurian YA","score":0.762,"slug":"arthurian-ya"},{"label":"Historical YA Fantasy","score":0.7579,"slug":"historical-ya-fantasy"}],"reader_fit":["Good for readers who enjoy Viking Romance","Good for readers interested in teens","Good for fans of Fantasy"],"related_lists":[],"series":null,"similar_books":[{"authors":["Alexandra Bracken"],"book_id":"9780593481653","cover_image_url":"https://img.bookfrontier.com/9780593481653.jpg?v=20260418T162306Z%3A2026-04-18T23%3A16%3A50Z","score":13.735,"title":"Silver in the Bone","url":"https://bookfrontier.com/books/9780593481653"},{"authors":["Alex Irvine","Alexander C.
