The Impossible Times trilogy

A teenage math prodigy named Nick Hayes navigates through life while battling cancer in 1980s England. Along with his group of friends, he spends time playing Dungeons & Dragons and grappling with quantum physics problems that blur the line between games and reality. Time travel enters the story as Nick discovers he can move between different periods, which forces him to confront paradoxes and make impossible choices. His decisions ripple across multiple timelines, affecting both his past and future selves. The series combines elements of science fiction, coming-of-age drama, and thriller genres while exploring themes of friendship, sacrifice, and the nature of time itself. Through intricate plotting and scientific concepts, the trilogy examines how small decisions can create vast consequences across parallel realities.

Readers praise the trilogy's scientific concepts, time travel mechanics, and character growth. Many reviews highlight the tight plotting and satisfying resolution of complex storylines. The intricate puzzle-box nature of the narrative receives frequent mention, with readers noting how early details pay off in later books.

✦ Mark Lawrence wrote The Impossible Times trilogy while working as a research scientist in artificial intelligence, bringing technical authenticity to the time travel and quantum mechanics elements in the story. ✦ The series' protagonist, Nick Hayes, shares a key trait with the author - both were diagnosed with a serious illness that significantly impacted their lives (though different conditions). ✦ The game Dungeons & Dragons plays a crucial role in the plot, with the characters' D&D sessions often mirroring or foreshadowing real events in the story. ✦ The trilogy was self-published by Lawrence, unlike his other fantasy series, yet still achieved significant commercial success and critical acclaim. ✦ The physics concepts explored in the books, particularly regarding parallel universes and temporal paradoxes, are based on actual scientific theories, including the Many-Worlds Interpretation of quantum mechanics.
