THE INVISIBLE LIBRARY is a book that I've been curious to read for a while now and I was quite happy when I got the chance to read it. I mean how can you not, if you are a bookworm, find the description of the book tantalizing? A Library that collects fiction from different realities. The book is intriguing right from the start as we get to know Irene who is on a mission to retrieve or rather steal a book. Finding rare books is what Irene and others that work for the Library do, they blend in and steal books and especially rare books that only exist in one reality or differ in another reality.

However, her new mission is cloaked in mystery and danger and she also gets a new assistant Kai, who has his own secrets. They are sent to an alternative London to retrieve a dangerous book. But, the mission quickly turns into a dangerous fight for their lives. And, it seems that an old rumor about a renegade collector from the Library is more than just a rumor.

I think THE INVISIBLE LIBRARY was quite a charming steampunk book. I liked the idea of an invisible Library with lots of mysteries. For a first installment in the series, this one felt like a brilliant appetizer for future books. You get to know its main characters, the mission is interesting and the ending of the book left me with want for more. I came to like Irene, Kai and detective Vale (he reminded me quite a lot of Sherlock Holmes) very much, and I'm looking forward to reading the next book in the series. I especially want to know more about Irene, Kai, and detective Vale. They are all very complex characters with secrets, and I want to know more about Irene's past, and Kai's family and Val's complicated relationship with his family.
