"A colossal achievement...a genre-crossing delight... Publishers dream of novels that appeal to habitual readers and to those seeking one big book to last a holiday, and that is what Zafon's quartet has delivered. His trick is to have linked multiple genres - fantasy, historical, romance, meta-fictional, police-procedural and political - through prose of atmospheric specificity." – The Guardian
"Carlos Ruiz Zafon is a gifted storyteller who knows how to capture his readers' attention. Packed with suspense, The Labyrinth of the Spirits is a gripping edge-of-your-seat thriller. As you read this chilling thriller, you feel as if your pounding heart is missing a beat." – Washington Book Review
"Intricate and sublime." – O: The Oprah Magazine, 15 Favorite Books of 2018
"A mystery, a love letter to books, and a magical adventure all wrapped up in one, this book is a masterful work of literature that will invigorate your love of reading." – Bustle
"A gripping and moving thriller set in Franco's Spain that's fully accessible to newcomers....29-year-old Alicia Gris, a capable, insightful operative working for the Spanish secret police...will remind readers of Lisbeth Salander... Fans of complex and literate mysteries featuring detectives with integrity working under oppressive and corrupt regimes will be well satisfied." – Publishers Weekly, Starred Review
"Ruiz Zafón clearly has had a great deal of fun in pulling this vast story together...His ability to keep track of a thousand threads while, in the end, celebrating the power of storytelling is admirable.... A satisfying conclusion to a grand epic that, of course, will only leave its fans wanting more." – Kirkus Reviews, Starred Review
"A compelling, multi-faceted, and haunting work of art told by a master storyteller. To say that the writing is brilliant is an understatement. Carlos Ruiz Zafón respects every word, taking his time to develop and do justice to the major, minor, and irrelevant characters, places, things, or situations in order to recreate a dark time in Spain's history and ensure that the reader not only bears witness to it but is immersed in it and feels it...An epic novel that is also an ode to writing and to the undying thirst for knowledge through reading." – Historical Novel Society
"Gothic, operatic, and in many ways old-fashioned, this is a story about storytelling and survival, with the horrors of Francoist Spain present on every page. Compelling...this is for readers who savor each word and scene, soaking in the ambience of Barcelona, Zafón's greatest character (after, perhaps, the irrepressible Fermín Romero de Torres)." – Booklist
"It is a bittersweet return to Barcelona for fans of Zafón, as he concludes his internationally beloved, labyrinthine Cemetery of Forgotten Books series (The Shadow of the Wind, The Angel's Game, The Prisoner of Heaven) with an operatic finale, drawing together all the threads as a rare book unveils a conspiracy that runs through Spanish history." "The plot is exquisitely intricate, like an elaborate steampunk timepiece. Alicia, a fragile but ferociously formidable, vampire-like seductress, is unforgettable. The pacing is exceptional, with its incessant, rolling waves of tension. Even the dialogue is remarkably sharp and fresh...The Labyrinth of the Spirits is a masterpiece...Readers' one regret will be that Labyrinth is the last in this ingenious cycle." – BookPage
"THE LABYRINTH OF THE SPIRITS is the sublime culmination to a truly outstanding series. Set in Barcelona from 1938 through the 1970s, these books deftly combine the world of bookselling, the long shadow of the Spanish Civil War, gothic literary interplay, wonderfully salty characters, sublime dialogue and verbal sparring, along with elaborate and satisfying exposition. Taken together or individually they represent a reading experience not to be missed...reading Labyrinth first would have given a sublime insight into any of the other books...As long as you actually open a door to the labyrinth and enter it, all is well. As to not reading the Cemetery of Forgotten books at all, that is obviously a grave error."

"Zafón is a master storyteller, combining the postmodern and the traditional in an enchanting hymn to literature...Magnificent...A dizzying tale of drama, intrigue and passion." – The Mail on Sunday (UK)
