Mattias was born in Sweden and grew up in Vejbystrand, an idyllic fishing village on the west coast. He studied microbiology at Lund University and molecular biology at the Karolinska Institute School of Medicine in Stockholm and the European Molecular Biology Institute in Heidelberg, Germany. He moved to California in 1999 and, in 2002, graduated from the Thomas Jefferson School of Law in San Diego.
Although he spends most of his days drafting mind-bogglingly boring contracts, he has always had a keen interest in fiction writing that was initially encouraged by an amazing middle school teacher.
The Guild of Thieves is Mattias' second published book, a historical young adult novel that takes place in the fictional Kingdom of Selenia. His first published novel, Arrow's Fate (available on KDP), follows a group of young Norse men and women on an epic journey through medieval Europe and the Middle East.
Mattias lives in Rancho Santa Fe, California, with his wife.
