Martta Kaukonen on the SPIEGEL BESTSELLER list!

We are thrilled to announce that just one week after its publication in Germany, FOLLOW THE BUTTERFLY aka THERAPIERT (Heyne Verlag) by Martta Kaukonen has entered the German bestsellers lists! Currently, it is on place 15 of the SPIEGEL BESTSELLER LIST for paperpacks – and German publisher Heyne have already ordered a second edition! What a start for the book on the German market!

Readers have been buzzing about the book as well:

Martta Kaukonen constructs a masterfully narrated psychological thriller, that doesn’t cease to amaze us as it gradually reveals more and more of its characters’ secrets. FOLLOW THE BUTTERFLY is a somewhat different, very psychologically constructed thriller, that convinces with soft tones and big feelings. Exciting until the very last page.” – Silke Schröder on

Nothing is as it seems. The topic of therapy takes center stage and offers readers an exciting insight into the depths of the human psyche – a truly successful thriller!” – myautumnofbooks

The ending then even outdid all the previous twists. After finishing the book, I was left with a feeling of “Wow!”.” – JS Booklover

Congratulations to Martta Kaukonen and Heyne for this impressive achievement!
