Magnus Chase - The Ship of the Dead

Book Three featuring Magnus Chase finds him basically killing himself over and over at the behest of Percy Jackson.  Luckily for Magnus, the pain is only for a bit until he wakes up again in Valhalla whole and complete.  Unfortunately, he will not have that option once he takes off on his quest to stop the Ship of the Dead.

Loki is trying to free the Ship of the Dead so he can go ahead and get started with destroying the Nine Worlds.  It is up to Magnus and his favorite Valkyrie, Dwarf, Elf and his einjerjar buddies to stop him before it is all to late and Ragnarok  begins.

Filled with Nordic mythology, a bit of mystery and plenty of adventure.   There is a little surprise relationship that develops that is very unique and made me stop and think but I really like the twist and am interested in where it will go.

The Hammer of Thor by Rick Riordan

Magnus Chase has settled into his life in Valhalla, as well as anyone can settle into a life, or afterlife, of an einjher.  Then Thor loses his hammer, the one he rules the world with, the one that keeps the earth giants under control, you know, the important one.
The second novel in the Gods of Asgard series is very good.  Funny, fast paced and has a wealth of information about the Norse gods and goddesses.  Highly recommended and not only for the young adult reader.
