Genevieve Cogman’s The Invisible Library is a fun, whimsical story following a librarian on a mission to collect books from different realities. The librarian, Irene, is given her first apprentice Kai. We follow them into this other world on a quest to retrieve a specific book for the library. They have to deal with several obstacles and they end up playing detective in order to find what they are looking for. This book is fast paced and I couldn’t put it down. I haven’t read anything quite like this, so it was refreshing to read something that hasn’t been overdone. Cogman’s influences shine in this novel. Her love for books really brings the story to life. This is a great read about a character that also enjoys the reading life. It feels very meta. Cogman makes many references to beloved characters and authors, such as Sherlock Holmes. This one will make your literary heart happy.
