Hollow City

Hollow City (2014), a fantasy novel for young adult readers by Ransom Riggs, is the second novel in the series that began with the celebrated Miss Peregrine's Home for Peculiar Children, picking up where the first installment finished. The next book in the series, Library of Souls, was released in 2015.

Hollow City opens with Miss Peregrine's peculiar group of children fleeing the evil hollowgasts in a boat on a storm-addled sea. Tossed and turned and facing imminent danger, they set out to find dry land. They arrive on a deserted beach, initially assuming the threats of the hollowgasts and bad weather are behind them. However, they soon discover other evil creatures—the wights—are in hot pursuit, so the children run into the forest. Before long, they realize that they have nowhere else to hide and must depend on the cover of the woods. Wandering around, they come upon a statue they recognize from the book The Tales of the Peculiar. With the knowledge they acquired from the book, they escape into a time loop connected to the statue.

Inside this loop is a menagerie of peculiar animals. The animals are grateful to the children for killing a hollowgast that had once infiltrated the time loop and threatened them. The children then find out that a Miss Wren is in charge of this time loop; Miss Wren is an ymbryne, someone who can manipulate time and assume the form of a bird. She has flown off to London to rescue other ymbrynes in trouble. The children believe she is the only one who can save Miss Peregrine, who is trapped in falcon form, and turn her back into a human.

The group joins forces with a band of Gypsies, and they travel together to London. They encounter trouble at the train station, where wights abduct them, holding them at gunpoint in a shed. Fortunately, Hugh evades capture and unleashes the bees in his stomach. The bees attack the wights, and the group boards the train. However, once on the train, they make a startling discovery: Miss Peregrine (in bird form) had previously—and accidentally—been left on board in a trunk.

The children witness the devastation wrought on London by World War II. With their knowledge of the time loop, they know the peculiarities that distinguish Miss Wren's particular flock of pigeons. They keep their eyes peeled for signs of these birds. They encounter a peculiar girl, Sam, who does not survive her war injuries.

The Tales of the Peculiar guides them to Saint Paul's Cathedral and a subterranean crypt located there. They meet a pair of peculiar brothers, Peter and Joel; they are echolocators who appear to share one mind. Peter and Joel know where the pigeons are and take the children there. Emma, Horace, and Jacob are the only ones from the group who follow the sounds of wings to the attic.

The attic houses Melina Manon, an angry teenage peculiar with telekinesis. At first, she is suspicious of the children, but Horace proves to her that they, too, are peculiar, and she asks to go with them. She informs them she has a peculiar pigeon that can lead them to Miss Wren. The children agree, and they follow the pigeon to a time loop, where they find Miss Wren. Unfortunately, Miss Peregrine, trapped in the falcon's body, attacks and kills the pigeon leading the group to Miss Wren.

Miss Wren is secreting herself in a building that is coated in a thick layer of ice. This way, the wights won't be able to enter. She agrees to help Miss Peregrine reassume human form, but it is an undertaking that will take all night.

As Miss Wren works on Miss Peregrine, Emma, Jacob, and Millard figure out that the wights are removing peculiar souls to feed them to hollowgasts, which then gives hollowgasts the ability to travel into time loops.

Miss Wren changes Miss Peregrine back into a human. Except it's not Miss Peregrine. It is her brother, Caul—a wight. It was he, and not Miss Peregrine, that the children initially rescued. All along, he was the one following them in hopes of entering Miss Wren's time loop and tracking her down. Up until that point, Miss Wren was the only ymbryne that had escaped capture, but now Caul has the opportunity to nab her. He summons the other wights, and they descend on the building, kidnapping all of the peculiars. As the wights march the peculiars away in handcuffs, Emma melts off her and Jacob's cuffs. They escape to a present-day phone booth. Jacob pulls out his cell phone and contacts his father. In the process, Jacob learns he has another peculiar talent: he can not only see hollowgasts, but he can communicate and control them, too.
