They quickly realized that they shared a passion for stories with young adults in the lead roles, and soon the idea to write a book together was born. The story took shape and when the idea came up to make the main characters young girls who also are witches, everything fell into place. The Circle and Fire, the first and second parts in The Engelsfors Trilogy, were released in April 2011 and April 2012. Part three, The Key, will be published in late 2013.

  • 2011 – The Circle (Cirkeln) young adult fiction



"What a stunning novel. Raw, real, smart, very thrilling and very, very wicked. The Circle is Twilight by way of The Girl With the Dragon Tattoo."

Lev Grossman, bestselling author of The Magicians


"The Circle is a story about group dynamics, identity, and finding one's place in the world. Like all great books, it's about how people handle the difficult task of becoming human beings, together with other human beings."

John Ajvide Lindqvist, bestselling author of Let the Right One In


"The Circle ensnares you from the start, with all the epic mayhem and darkness of Buffy the Vampire Slayer and with teen characters as rich and nuanced as any reader could hope for. It's an utterly convincing world, and a resonant one, and we find ourselves wanting to follow its heroes anywhere."

Megan Abbott, bestselling author of Dare Meand The End of Everything


"A beautiful, frightening, empowering novel reminiscent of the best of Scott Westerfeld or Anne Rice, The Circle puts its mismatched heroines—and readers—at the center of an ancient conspiracy of magic as terrifying as it is realistic. Enthralling from start to finish."

Elizabeth Hand, bestselling author of Available Dark and Waking the Moon


Reader's comments

“This is a book one empathizes with to one hundred percent.”


"Honestly, one of the best books I've ever read."


"Run to your school library and ask the librarians to order in The Circle, then run to your town library and ask the librarians the same thing, or buy the book wherever you can get it."


"This success, which just recently started, I want to follow to its goal. If there is a goal, that is."


"To illustrate just how good I think The Circle is, I can tell you that despite that I get terribly carsick, I still had to finish reading the last chapter on the bus on the way home from work. I had to put the book down several times because I began to feel sick, but I was just obsessed by knowing how it would end."


"You just throw yourself over the text and both want it to (you need to know how it eeeends) and not want it to (because it's so goooood) end."
