The Sword of Summer

The Sword of Summer is the first book in the series, released on October 6, 2015, as a hardcover, e-book, and audiobook.^[5] The novel is narrated by Magnus Chase, a homeless Bostonian orphan, who learns he is the son of a Norse god at first knowing from his uncle. On the same day, he is confronted by a fire giant named Surt, who wishes to claim a sword called "Sumarbrander" (the "Sword of Summer", or "Jack"). In the fight, Magnus is killed and carried to an ancient interpretation of the Norse afterlife, named Valhalla, by a Valkyrie named Samirah "Sam" al-Abbas. With the help of Sam, a dwarf named Blitz, and an elf named Hearth, Magnus ruins the giant's plans to free the Fenris Wolf and hasten Ragnarök.^[8]

The novel has been well-received since its publication, but was not a "big front-runner" among other bestselling books in 2015.^[9] It debuted at #1 on the New York Times Children's Middle Grade Hardcover Best Sellers list, and rose to #3 on Amazon's best-selling Children's Books list for 2015.^[10][11][12] It also won the Goodreads Choice Award for Middle Grade & Children's books in 2015.^[13] The Sword of Summer has been especially praised as an excellent continuation of author Rick Riordan's writing style, although some critics have expressed regret that the book only meets the expectations of fans, rather than surpassing them.^[14][15]

The Sword of Summer was later published in several foreign-language editions, as well as a UK edition with the same title (published by Puffin Books). Its foreign-language editions include ones in Spanish, Portuguese, Italian, Turkish, Dutch, German, Bulgarian, Finnish, Polish, French, Norwegian, Chinese, Czech, Russian, Romanian, Indonesian and Hebrew. While the U.S. editions have cover art by illustrator John Rocco, most foreign editions have unique art created by other artists and illustrators.^[16] In the U.S., several unique promotional editions were released by different booksellers during the initial publication; the mass-merchandiser Target, for example, released its books with an included poster of the Nine Worlds of Norse mythology.^[17]

They are greeted by the gods when they arrive in Vigridr, after sailing the currents that Naglfar, the ship of the dead, would have sailed. Magnus and Alex take Randolf's old mansion and make it "The Chase Space", a home for homeless children.

Hotel Valhalla: Guide to the Norse Worlds

Hotel Valhalla: Guide to the Norse Worlds is a supplementary work for the Magnus Chase and the Gods of Asgard series, consisting of background information on the gods, monsters, dwarves, and elves that are featured in the main series.^[19][20] It was published as a hardcover on August 16, 2016.^[21][22][23]

The introduction is written by Helgi, the hotel manager. He welcomes new residents and thanks them for their sacrifice. He then explains that the book is meant to answer any questions they may have about the experiences of their new existence, and asks that they consult the book before bothering him.^[24]

The next section, titled “What in the Worlds?” is written by Hunding the bellhop. He doesn't really want to write anything for the book, but his boss Helgi is making him do it. He explains the universe from the Norse perspective: nine worlds held in the branches of Yggdrasil the World Tree. The first of these worlds, Asgard, is home to the Aesir, and the location of Hotel Valhalla, where Odin's einherjar live. Vanaheim is the home of the Vanir, and the ream of Folkvanger, the peaceful Norse afterlife. Midgard is the Norse name for Earth, home of the humans, and is connected to Asgard by the Bifrost. Alfheim, ruled by Frey, is inhabited by light elves. There is no night in this world. Jotunheim is inhabited by the jotun, or giants. It is covered in mountains, snow, and ice. Nidavellir is home to the dwarves, and is very gloomy, chilly, and dark because it is entirely underground. Muspellheim houses the fire giants and demons, and resembles the sun. Niflheim is inhabited by the frost giants, and is cold and foggy. Finally, Helheim is the realm of Hel and the dishonorable dead. Hunding also describes the Ginnungagap, the void between the worlds, and the Norse creation story.^[24]

Hunding's description of the nine worlds is followed by sections describing some of the Norse gods and creatures, most accompanied by a supplementary short story, interview, poem, or note. The list of gods includes Odin, Thor, Loki, Frey, Freya, Skirnir, Mimir, Hel, Heimdal, Ran, Frigg, Balder, Hod, Idun, Honir, Tyr, Uller, and Njord. Hunding lists the homeworld of each one, as well as their physical description, family members, and what they are best known for. A few of the better-known gods also get a few extra facts thrown in. Snorri Sturluson manages to get interviews with a few of the gods, while others get short stories. Frey gets to have a rap battle with Jack the sword, and Frigg answers questions in a weekly advice column.^[24]

The list of mythical beings includes Surt, Ymir, Utgard-Loki, Gerd, Elves, dwarves, Valkyries, and the Norns. Each entry includes the being's classification, homeworld, appearance, and what they are best known for. The extra material includes a threat from Surt, a poem by Gerd, a message from the Alfheim news team, diary entries, and a few short stories.^[24]

Next, Hunding (who's really getting tired of having to write the book at this point) lists the fantastic creatures of the Norse world. He addresses Nidhogg, the eagle of Yggdrasil, Ratatosk, Heidrun, Eikthrymir, Saehrimnir, Sleipnir, Jormungand, Fenris wolf, and Thor's goats, Otis and Marvin, explaining what they are, where they live, and why they are noteworthy. Ratatosk manages to fit in some insults, Sleipnir tells the story of how Loki gave birth to him, and Marvin includes some tasty recipes for goat meat, while Njord provides some lullabies written by Frey that are useful in keeping Jormungand asleep.^[24]

Helgi closes the book, urging the readers to consider all the possibilities that their afterlife affords them. He again strongly discourages them from asking him any questions. A pronunciation guide and glossary are also included.^[24]
