Magic comes naturally to Rudeus Greyrat, a young boy whose memories belong to a 34-year-old man from another world. He develops his remarkable talent under the mage Roxy Migurdia, studies swordplay with his father, Paul, and finds a close friend in Sylphiette, a girl his own age.
Before this new life, he was a shut-in who had endured years of bullying and cruelty. An attempt to act heroically ended in a tragic accident, after which he awoke as a baby with two loving parents. His adult knowledge helps him adjust, but starting over also means confronting the trauma he still carries. Determined to make use of this second chance, Rudeus hopes to build a fuller life—and perhaps find the love that eluded him before.
