KAREL SCHRIJVER is an astrophysicist studying the magnetism of stars, in particular of the nearest star, our life-enabling Sun. Together with his wife, a physician, he wrote "Living with the stars", about the connections between the human body and the Universe. The discovery of exoplanets and the unfolding of fascinating insights into distant worlds triggered his popular science work "One of ten billion Earths".

His most recent book, "The White Prison," is a first-contact sci-fi novel. In this standalone sequel to the author's IMMERSION, astronauts inhabit a comfortable AI-generated world while they explore the hostile real-world setting of Saturn's moon Enceladus. Once they learn to communicate with the alien life form, they find striking parallels between the Enceladeans and themselves. When the probe's crew discovers the foundation of Enceladus' ecosystem, they have to decide how to protect Earth and Enceladus from greed, destruction, and all-out war.
