"Maten är min medicin" by Janesh Vaidya. This book is actually vegetarian but it's super easy to modify the recipes to be vegan.
"VÅR KOKBOK vegan"
"Vego Hela dagen " by Mattias Krisstiansson.
The first three ones are Swedish. The "VÅR KOKBOK vegan" is not the fanciest looking and not filled with beautiful pictures of the dishes but the recipes tastes sooo goood! I highly recommend it and please don't let it down because of the not so fancy design. It contains one of the favourite recipes in our family.
The book "Vego hela dagen" is actually for teenagers but I think it's a perfect source for day-to-day recipes. They are simple and delicious and contains a beluga bolognese that we often cook in our family.
My final tip is actually not a book but a Swedish Magazine. It's incredible inspiring and I recommend anyone who is curious to try the vegan diet to buy this magazine and start cooking!
