Jäniskerroin The Rabbit Factor

What ought one do with one’s life? Insurance mathematician Henri Koskinen knows the answer because he calculates everything down to the very last decimal.

Then everything changes. After suddenly losing his job, Henri inherits an adventure park from his brother – its peculiar employees and troubling financial problems included. The most dire of these financial problems appear to originate from big loans taken from criminal quarters, now keen to get their money back.

In the adventure park, Henri also crosses paths with Laura, an artist with a checkered past. As the criminals begin to collect their debts and as Henri’s relationship with Laura deepens, he finds himself faced with situations and emotions that simply cannot be pinned down in his spread sheets.

The first installment in a forthcoming trilogy, The Rabbit Factor is a darkly comic novel about love, death and insurance mathematics.


  • “How unassumingly, almost starkly, and yet so beautifully Tuomainen describes the awakening feelings that Henri has in the brand new arena of romance! The plot unfolds pleasantly as secrets are gradually revealed. /…/ The story concludes happily leaving the reader both in great spirits and with profound thoughts about life’s peculiarities. /…/ Tuomainen’s humor is dry and sharp, in itself mirthful, and it succeeds in describing human beings and our times with enjoyable wit.”

    Kirsin Book Club, Finland

  • “The true gems [in The Rabbit Factor] are Henri’s discussions and confrontations with the employees of the adventure park as well as his meetings with gangsters. /…/ The plot elements come together superbly as Tuomainen sure knows how to handle the quick twists and turns. /…/ The last pages leave a wonderful aftertaste and hence The Rabbit Factor qualifies as my favourite Tuomainen novel, alongside The Man Who Died. The use of language and the flow of sentences tickle and please. The story grips you in a way that I had to read it all in one go.”

    Tuijata Kulttuuriblogi, Finland

  • “Antti Tuomainen is the master of creating moods and universes that are realistic yet extremely quirky. /…/ As comical as the character of Henri is, he is also lovable. The Rabbit Factor is a love letter to mathematics and logical thinking. /…/ The Rabbit Factor offers guaranteed entertainment to friends of Tuomainen and of black humor.”

    Amman lukuhetki, Finland

  • “The clash between Henri’s personality and the adventure park is delightful and creates an altogether hilarious tension in The Rabbit Factor. Tuomainen has written quite an array of people into the novel, whose characteristics are superbly feasted upon. /…/ I happily co-sign The Times’ statement that Tuomainen is the funniest writer in Europe.”

    Kirjanurkka, Finland

  • “Rationality and emotion, death and humor – playing with opposites could easily lead to narrative problems. However, Tuomainen handles it all with perfection. /…/ The rhythm is tightly controlled. /…/ This is like listening to the most perfect jazz session.”
