Ransom Riggs is a #1 New York Times bestselling author who studied literature at Kenyon College and film at the University of Southern California. He created the Miss Peregrine's series after collecting vintage photographs and using them as inspiration for his narratives, blending haunting imagery with fantasy storytelling. Riggs lives in Los Angeles with his wife, bestselling author Tahereh Mafi, and completed Library of Souls as the concluding chapter of the original trilogy.

Library of Souls is ideal for young adult readers who enjoy dark fantasy, time travel narratives, and stories blending vintage photography with supernatural elements. Fans of the first two Miss Peregrine's books will appreciate this conclusion to Jacob's journey and the resolution of the ymbryne kidnapping storyline. Readers who love gothic atmospheres, morally complex characters, and imaginative world-building with Victorian-era settings will find this book particularly engaging.

Library of Souls provides a thrilling conclusion to the original Miss Peregrine's trilogy with high-stakes battles, shocking betrayals, and the revelation of the Library of Souls itself. While some readers feel the ending leaves certain character relationships, particularly between Jacob and Emma, somewhat unresolved, the main storyline wraps up satisfyingly. The book successfully raises the stakes by introducing new world-building elements like Devil's Acre and the soul jar mythology while delivering action-packed sequences.

Devil's Acre is a dilapidated Victorian-era slum where peculiars engage in crime, slavery, and drug trade, serving as the most wretched location in peculiar history. This dangerous district is controlled by wights and features peculiars addicted to ambrosia, a power-enhancing drug that melts users' faces after excessive use. Jacob and Emma must navigate this corrupt underworld to locate their kidnapped friends, encountering death matches between peculiars and hollows along the way.

The Library of Souls is a legendary, supposedly non-existent place where the souls of peculiars are stored in jars after death, functioning like a checkout system where peculiars receive souls at birth and return them upon death. Located in the Abaton loop, this mystical library becomes Caul's ultimate target because consuming these souls grants immense power and abilities. Jacob discovers he possesses his grandfather's rare ability to actually see the soul jars hidden within the library, making him essential to Caul's evil plans.

Jacob's newfound ability to control hollowgasts, not just see them, transforms him from a passive observer into a powerful weapon against the wights. This power proves crucial during the climactic battle at Caul's Panloopticon fortress, where Jacob commands all captured hollows to fight alongside the peculiar children. His unique gift, inherited from his grandfather, also allows him to see soul jars in the Library of Souls, making him the only person capable of accessing the library's power.

Bentham is revealed as Miss Peregrine's brother and the man responsible for the original Siberian explosion that created hollowgasts and wights. Initially appearing as Jacob and Emma's savior and ally, Bentham ultimately betrays the peculiar children because Miss Peregrine refuses to forgive him for his past mistakes. In the final confrontation, Bentham consumes soul jars alongside his brother Caul, transforming into a giant monster who battles Caul before both perish when the Abaton loop collapses.

Ambrosia is a dangerous drug in Devil's Acre that peculiars pour directly into their eyes to dramatically strengthen their abilities, but prolonged use melts the user's face. This substance has created a culture of addiction and death matches where peculiars enhance their powers to fight hollows and other creatures for entertainment. The drug represents the dark underbelly of peculiar society, showing how desperate peculiars exploit their gifts for survival in Devil's Acre's corrupt environment.

After defeating Caul and Bentham by destroying the Abaton loop and the wights' fortress, Jacob makes the difficult decision to return to his normal life in the present day. Jacob and Emma promise to maintain their relationship through letter-writing despite being separated by time, leaving their romantic future uncertain. While this conclusion resolves the main conflict against the wights, some readers find the character development and relationship arcs feel incomplete, suggesting the story continues beyond this trilogy.

Some readers found Library of Souls to be their least favorite book in the trilogy despite its thrilling plot, citing difficulty maintaining engagement even with abundant action and peril. The ending has been criticized for feeling incomplete in terms of character development, particularly regarding Jacob and Emma's unresolved relationship, making it seem less like a definitive conclusion and more like a pause in the story. However, reviewers praise Riggs' writing style and appreciate how the book adds depth to peculiardom's world-building with new concepts like Devil's Acre and the soul mythology.

Library of Souls introduces significant world-building elements including the corrupted peculiar society of Devil's Acre, the mythology of soul jars and their connection to peculiar powers, and the revelation of Miss Peregrine's family history. The book deepens the lore by explaining the origins of hollowgasts through Bentham's backstory and revealing that peculiar souls are tangible entities stored in a mystical library. These additions make peculiardom feel more realistic and complex, though the story continues in later books rather than truly concluding with this volume.
