Nineteen years ago, something happened between Harry Potter and Draco Malfoy-something only Draco remembers. Determined to take the secret to his grave, he's thrown into chaos when fate reunites them at Hogwarts. Freshly divorced and navigating his new role as a professor, Draco is already struggling. But with his son, Scorpius, forming an instant bond with Albus Potter, and Harry-newly single-returning as well, Draco's carefully constructed walls begin to crumble. As Albus and Scorpius tackle their first year of magic and mayhem, they decide their fathers are long overdue for a happily-ever-after. Alongside an unlikely team-including Astoria and Ginny, a retiring Minerva McGonagall, new professor Teddy Lupin, Headmaster Neville Longbottom, and the ever-insightful Luna Lovegood-they set out to mend old wounds, reveal buried truths, and maybe, just maybe, give love a second chance. Hogwarts has always been a place of magic, but for Harry and Draco, it may just work the most powerful spell of all-one that rewrites the past and reshapes the future.
