Postcards from Valhalla is about a 15 year old boy named  Viggo. His father passed away when he was 10 after he went off grid. The same location his brother Magnus has now gone missing. While he wants to go see the new Thor movie with his friends his mother already bought tickets to Shetland to find his brother Magnus. On the way they get to meet a strange passenger who doesnt seem to want to leave their side and who has strange stories about himself that do not always add up. But that is not the only strange thing happening as they are at Shetland as Viggo gets visions about vikings who used to live in Shetland.

This was such a strange but intrigueging read. I could not put it down. I kept telling my friends, its strange, i dont get it but i kept going, i kept wanting answers and boy oh boy did we get the answers. The book is packed with some Norse Mythology and if you got the knowledge on that it is fun to read it and you will absolutely remember things. 

Normally i dont really read these kind of books as im normally a romantasy reader and there is a very minimum to no romance in this book. I honestly didnt mind it at all. It was surprisingly good and the ending was kind of what i thought but also not really. 

I really loved the writing style, it was paced up right with not too many details on things! At same time you get to know a bit about Edinburgh and Shetland and it makes me itch to go back and not just visit Edinburgh but Shetland too😂

Overall absolutely worth the read if you like Norse Mythology!
