If you are looking for something new and intriguing - I recommend checking out ANYTHING by Haruki Murakami - you will not be disappointed. I recently wrote a review about his latest novel The Strange Library, which you can read here! Some of my favorite titles are: Sputnik Sweetheart, Norwegian Wood and The Wind-Up Bird Chronicle.
If you are looking for a classic - here I would normally recommend my favorite book of all time - The Picture of Dorian Gray, but why not pick up something holiday related like A Christmas Carol by Charles Dickens - it is a great holiday read and surely will get you right in the mood for the festive season. It is also something that I think everyone should have in their library. It is a staple book.
If you are looking for a young-adult novel - definitely pick up Althea and Oliver by Cristina Moracho. I wrote a full review of it here. It is definitely my favorite from this year of all the young-adult that I read. It is an interesting, raw, compelling story that really pushes the boundaries of young adult. It started off similar, and contemporary like The Fault in Our Stars, but it definitely moves beyond that quite quickly. Please pick it up, read it and love it.
If you are looking for a comic/graphic novel - I recommend Black Widow Vol 1. which I also reviewed here! It is by far my favorite graphic novel yet. The artwork is stunning and the storyline is super interesting. I really enjoyed it! And I think that this would be enjoyed even by those who aren't familiar with the marvel-verse.
If you are looking for a bookish gift - I recommend a bookmark from the lovely shop craftedvan on etsy. They make the cutest magnet bookmarks ever! I own so many from them and they are wonderfully crafted and just stunning. They are also reasonably priced and will make any book lover incredibly happy. They also take custom orders if you can't find anything in the shop that you don't like!
Well that's it from me this year! I hope that these suggestions are helpful! :D Happy Holidays all and happy reading! <3
