Here’s what the German publisher said:

I have never read a thriller like this. A female serial killer whom we root for and not one unreliable narrator but four whose narratives are woven into each other with such skill. This plot-driven, emotional and wonderfully written book is what our readers have been waiting for.
– Janina Dyballa, Editor, Heyne Verlag, Germany

The very first rights for the title were sold only yesterday to Estonia (Hea Lugu).

GUIDE ME, BUTTERFLY is an exciting debut thriller about a 20-year old female serial killer Ida, that starts visiting a celebrity therapist, to avoid a seemingly inevitable jail sentence.
Told by 4 different narrators, the story unfolds and twists in neck-breaking speed, not all is how it seems and even the most trustworthy people can let you down.

”Kaukonen succeeds in tricking the reader time and again: just when you think you’ve figured it out, the narrator changes and the tables turn.”
– Maaseudun tulevaisuus newspaper

by Martta Kaukonen

An addictive psychological thriller in the spirit of Gillian Flynn

Ida, 20, a serial killer who was abducted as a child, starts therapy with celebrity therapist Clarissa. Only one of them knows that they share a mutual secret from the past. Will the other one realize it before she gets murdered?

Clarissa is a middle-aged psychotherapist, the best in her field. She is familiar to everyone from her TV appearances and from glossy magazines. For her, every patient is a princess. And someone only she can save. Or can she? Clarissa already has one suicide to answer for; a teenage boy’s death never seizes to haunt her.

When Ida becomes Clarissa’s patient, a cat-and-mouse game begins in which rules are followed by no one. The kind of game that never ends well.
