'Zijn haarscherpe schets van de gebroken zusterrelatie en hun voorzichtige toenadering doet recht aan het complexe samenspel van liefde, frustratie, verdriet, haat en moederinstinct. (...) Met grote beheersing balanceert hij tussen zelfreflectie en conflict, en dat maakt Veertig Dagen tot een loepzuivere roman.'

NRC Handelsblad



'Pieter Webeling’s debut tells the story of a very intense and twisted relationship between two sisters. What reads at first as a quite standard love story and family portrait, turns into an unusual and unexpected narrative of infidelity, manipulation and subsequent forgiveness only possible between close family members. The novel is an easy and light read, yet is a thoughtfully written novel as well, offering insight in the abyss that is the human condition and questioning the meaning of life and death without feeling overwrought. It touches upon moral dilemmas, suspending any kind of judgment.'
