As Albus and Scorpius begin their life together, Albus discovers that married life is every bit as wonderful and difficult as he always anticipated it would be. Life is better now that they're free from the looming threat of a Dark Arts resurgence, but Albus quickly realizes that there are plenty of other threats, too, like aggravating bosses and unexpected bouts of baby fever. Meanwhile, officials within the Ministry unearth a rapidly-worsening problem: for reasons unknown, the frequency of Squib births has quietly and suddenly quadrupled, leading to serious concerns over what might be prohibiting wizards and witches from passing on their magical genes-- and what that might mean for the coming generations of Wizardkind. While James and his new Ministry department struggle to deal with the societal impacts of an unprecedented amount of Squib children, Lily and Albus find their jobs--and their lives--intersecting in an unexpected way.
Scorpius Malfoy knew his fifth year would be challenging-- but he hadn't expected this. Between his impending O.W.L.s, his new relationship, Quidditch tryouts, the public eye, and the Slug Club, he can hardly catch his breath. Meanwhile, Harry Potter discovers that being a professor at Hogwarts is very different from being a student there-- especially when you've got three mischievous children and a handful of students who can't seem to do more than ogle at you.
Ginny Potter estimates it will only take three days into the Weasley-Potter family holiday for Albus to act on his feelings for his best friend. Albus estimates it will only take three days for him to die of embarrassment. And Scorpius, well. Scorpius is just glad to be there with Albus in the first place.
