It's been six weeks since Magnus and his friends returned from defeating Fenris Wolf and the fire giants. Magnus has adjusted to life at the Hotel Valhalla—as much as a once-homeless and previously alive kid can. As a son of Frey, the god of summer, fertility, and health, Magnus doesn't exactly fit in with the rest of Odin's chosen warriors, but he has a few good peeps among his hallmates on floor nineteen, and he's been dutifully training for Ragnarok along with everyone else. His days have settled into a new kind of normal. But Magnus should have known there's no such thing as normal in the Nine Worlds. His friends Hearthstone and Blitzen have disappeared. A new hallmate is creating chaos. According to a very nervous goat, a certain object belonging to Thor is still missing, and the thunder god's enemies will stop at nothing to gain control of it. Time to summon Jack, the Sword of Summer, and take action. Too bad the only action Jack seems to be interested in is dates with other magical weapons. . . .

Unraveling of the Prophecy

Thor’s hammer is missing again. The thunder god has a disturbing habit of misplacing his weapon – the mightiest force in the Nine Worlds – but this time the hammer isn’t just lost. It has fallen into enemy hands. If Magnus Chase and his friends can’t retrieve the hammer quickly, the mortal worlds will be defenseless against an onslaught of giants. Ragnarok will begin. The Nine Worlds will burn. Unfortunately, the only person who can broker a deal for the hammer’s return is the gods’ worst enemy, Loki — and the price he wants is very high.
The is a short and very minor prophecy about Blitzen read by Hearthstone through his runes.
Blitzen's friends turn him to stone to prevent dying from the wound.
Then they use the Skofnung stone to heal him before Thrym's wedding on OSTARA.
Randolph Chase stabs Blitzen with the Skofnung sword resulting in a lot of blood.

“At this point, most people would have thrown themselves down on the ground and given up hope. And by most people, I mean me.”

LOVED THIS SO MUCH. Rick Riordan just gets better and better with each series. This right here is proof that a book can be hilarious and fun and make the reader feel a whole range of emotions while also touching on some really important and relevant topics. I CAN'T BELIEVE THIS IS JUST A TRILOGY I NEVER WANT IT TO END BUT HOLY HELHEIM AM I EXCITED FOR THE NEXT BOOK.

What I love most about Rick's work is that the action and suspense just keep getting better! It's not like with most trilogies where you feel the second book is just a bridge to the third book and doesn't really add any value to the story. The Hammer of Thor gives us dynamic character growth, new characters to cherish, epic adventures, suspense and of course a cliffhanger ending!

Rick Riordan lo ha vuelto a hacer. De verdad, con cada libro de este señor que leo me enamoro aún más de su forma de escribir. Y sí, todos sus libros son iguales, pero es que me da igual. Como con todos los libros de este señor, ha sido un libro súper divertido y súper ágil de leer. Me lo he pasado genial reencontrándome con Sam, Magnus, Blitz y compañía; y me ha encantado saber un poquito más de Hearth, de su historia y de su mundo.
