Reading this, I couldn’t help thinking about the TV show The Librarians wondered which came first because they are very similar. Both are about a secret Library that sends its Librarians to alternate realities to bring back books for their collection. I think the show brought back more than just books, but you get the idea. The Invisible Library follows Irene, a junior librarian, who is given a mission and a new student after she has just returned from another mission. She and Kai head off to a different reality to find a book of Grimm’s fairy tales. They are immediately swept up in a mystery as the book has been stolen. A vampire has been killed. Fairies also want it and there are werewolves too. I really like Irene. She’s spunky and a little quirky. She’s quick-thinking and can easily adapt to any situation. She knows immediately that there is something not quite right about this mission but she is loyal to the Library so she doesn’t question it. Unlike the other Librarians, she was born into it. Both of her parents are Librarians. While she did attend a private school in Switzerland, her unusual upbringing, she is a bit awkward. I like the chemistry between her and Kai, her new trainee that she has to show the ropes. Kai is very eager to get out and start working. It’s kind of cute as to how excited he gets during their first fight. I understand why so many people like this series and I am looking forward to reading the rest of the series.
