A Map of Days

Jacob Portman is shocked by his friends' presence in modern day. With Miss Peregrine's support, he tells his parents everything. His father recounts a peculiar-related memory and says he wants to forget everything. He scolds Jacob for siding with Abe. Miss Peregrine wipes their memories. Jacob wants to leave his normal life behind, but she says he is meant for both worlds.

The children find Abe's shelter and log. Miss Peregrine takes them to the Devil's Acre. Sharon is now in charge of the Panloopticon, and the house has been turned into a terminal and shelter for peculiars. At the temporary headquarters of the Council of Ymbrynes, Miss Cuckoo and Miss Peregrine ask Jacob to speak about the battle with Caul to boost morale. After receiving a matchbook from Lester Noble Jr., Jacob calls the number and says he wants to continue Abe's work. He and Emma follow H's instructions to a diner and are sent into a loop, where a hollow attacks. Before they could kill it, H calls off the hollowgast Horatio and says Jacob is hired. H says he and Abe's group hunted hollows and rescued peculiar children. H gives them packages to bring to Florida and New York.

Jacob and Emma find a hidden passageway to Abe's cars and, along with Millard, Bronwyn, and Enoch, drive to Mermaid Fantasyland in Florida. They meet Paul, who leads them into a loop to escape police. At the Flamingo Manor, they give Billie a package and learn that wights killed most of the ymbrynes in America, leaving mostly demi-ymbrynes. They fight off the gang "police" from earlier, and Paul agrees to take them to a portal in his hometown, Georgia. On the way, Paul, who is black, refuses to enter a diner. Jacob realizes they are in the Deep South in the time of segregation.

They enter the loop in 1935 and meet Elmer and Joseph, who describe someone named Gandy and show Jacob a photo of a younger H and V, H's travel companion. Jacob discovers Gandy is Abe. Jacob gives Annie the other package. She tells them about the Organization, a group of normals who want to eradicate peculiars from the country, and gives him a matchbook bearing a North Carolina address. At the North Carolina restaurant, they receive instructions to bring a peculiar from a Brooklyn high school to loop 10044. Jacob and Emma agree to put their relationship on hold. The others call to say Miss Peregrine is looking for them.

In New York City, they stay at a hotel where Abe had also stayed, a loop. At J. Edgar Hoover High School, they meet Lilly, a friend of Noor, the peculiar. Lilly takes them to an abandoned warehouse. Jacob ignores H's order to abort the mission. They meet Noor, who absorbs and releases light to blind the armed men who attack them. The children escape. Brownwyn, who had been shot with a dart, passes out. En route to the hospital, they are lured into a restaurant and, except for Lilly, taken into a loop. They meet Frankie, who calls together the clan leaders of New York for an auction. The group is brought by 1920s gangsters to Leo Burnham, who reprimands the leaders for attending an illegal auction. Leo wants to execute Jacob because Abe killed Leo's granddaughter, Agatha, along with other children. Jacob believes wights framed Abe. Leo's sister Donna, the Baroness, convinces him to pardon them. Leo detains Noor, but Jacob is released and met by his friends, Miss Peregrine, and Miss Cuckoo. They go through a loop to the Acre.

Miss Peregrine says the ymbrynes were working on a peace treaty with the Clans, and the group's actions have set them back. Jacob calls H, who says Abe wanted Jacob to have a normal life. H says he has one last job before he retires, which Jacob senses has to do with Noor. Sharon invites Jacob to a meeting. Jacob accepts a ticket but says he is not going against the ymbrynes. Jacob finds H's apartment and a dying H, with Noor unconscious nearby. H tells him to take Noor and seek V, as Noor and six other peculiars are the seven prophesied peculiars. H says although he and Abe did not kill any children themselves, they are responsible for their deaths. H lets Horatio eat his eyes as he dies. Horatio turns into a wight and leaves them directions before jumping out the window. Jacob and Noor set out to find V.
