But what is time, and can it be influenced? With the help of a mouse clockmaker, a lot of inventiveness, and the notes of a certain famous Swiss physicist he succeeds in traveling back in time. But when he misses his goal by eighty years, the only one who can help is an employee of the Swiss Patent Office, who turned our concept of space and time upside down.  From the creator of Lindbergh–The Tale of a Flying Mouse, Moletown, Armstrong – The Adventurous Journey of a Mouse to the Moon, and Edison – The Mystery of the Missing Mouse Treasure comes Einstein. Torben Kuhlmann, in his fourth mouse adventure, explores the question: Suppose Albert Einstein’s famous theories first came into being through an encounter with a little mouse? Rave Reviews for Einstein: His unique ability to combine fun, facts, science and biography makes Einstein a real triumph. BookPage, Starred Review "As in Armstrong (2016) and Edison (2018), Kuhlmann employs a mix of narrative and fantastically detailed mouse’s-eye-view pencil-and-watercolor scenes to portray a small, furry investigator intrepidly tackling scientific and technological challenges in a human-sized world—here involving old records in a certain Swiss patent office, clock gears and computer parts, trial and error, and equations on chalkboards." - Kirkus, Starred Review
