FOLLOW THE BUTTERFLY now published in German!

Publication news! 

We are excited to announce that Martta Kaukonen’s international success crime novel FOLLOW THE BUTTERFLY is now out in German, published by Heyne this week! And we love their cover! 

THERAPIERT has already been praised by German bloggers:

The thriller was able to surprise me with many plot twists, fool me and was simply a great read, because especially the frequent changes between the different perspectives made me incredibly curious again and again and everything came together bit by bit and yet in suspenseful manner (…) Ultimately, in my opinion, a successful debut by the author and I am already incredibly excited to see what I can read from her next!” – Gedankenlabor blog

It’s exciting how the author succeeded in her novel to present the events as present, but the characters spoke to you as if they were reflecting on the events with us in a Netflix series. That was definitely the icing on the cake for me! (…) FOLLOW THE BUTTERFLY [was] a real page turner. Every twist hits you cold and every solution you come up with is destroyed by the author in one sentence. A thriller that will take your breath away. You can no longer trust your own thoughts and the individual characters. Recommended reading for psychological thriller fans!” – Lisa Albrecht on

Kaukonen’s debut novel is in its structure and narrative style reminiscent of thrillers by Gillian Flynn (amongst others “Gone Girl”), Paula Hawkins (“Girl on the train”) or A. J. Finn (“The woman in the window”). The novel really toys with the reader. (…) A clever game of confusion that draws its subtle tension from the constant changes in perspective and the numerous twists and turns. The special narrative style makes Kaukonen’s novel so worth reading. A psychological thriller that really gets under your skin and subliminally, but sometimes ironically, also criticizes the media and psychotherapy.” – Thomas Gisbertz on

Congratulations to Heyne and Martta Kaukonen!
