"A love story from hell" - The New York Times
"In Butterfly Skin, readers are not only treated to in-depth explorations through the psychologies of a diverse array of characters (all of whom come off as sickos or weirdos in their own right), but also a very Russian history lesson concerning its homegrown bad men." - Ravenous Monster
"This book is much, much deeper than just a story about a serial killer and a masochist who follows him." - Popcults
"If Stieg Larsson and Thomas Harris met each other on ICQ, courted each other, then met in person and had a lovechild and posted its picture on a creepy subreddit, it'd look something like this book". - Litreactor
"Kuznetsov's killer feels real and vulnerable in a way that does feel fresh." - Criminal Element
"Through his riveting plot and singular characters, Sergey Kuznetsov explores the sometimes pathological fallout resulting from our instant connectivity in the emerging world of emails, facebook, twitter, and other forms of electronic "intimacy." - Bloody Disgusting
"Superb character development and a strong central plot that will keep you enthralled." - City of Films
"386 pages of pure terror." - Bio Gamer Girl After Dark
"Fans of serial killer thrillers and of Russian novels in translation will find a lot to love, if they have a strong stomach." - Library Journal
"Readers who prize atmosphere and characterization over breakneck pacing will enjoy Kuznetsov's dark, quintessentially Russian tale. It's richly detailed, steeped in foreshadowing of inevitable tragedy, and offers a poetically twisted take on death. In addition, fans of The Girl with the Dragon Tattoo (2008) will appreciate Ksenia's character, which is reminiscent of that of Lisbeth Salander." - Booklist
"The book is sure to gain momentum globally and evolve from a cult phenomenon to a classic piece of literature" - Examiner.com
"The fainthearted had best stay away." - Publishers Weekly
