Book #1 - Super original, awesome characters. It sets up the world perfectly with humor, horror, and mystery,
Book #2 - A fun continuation of the story, and the old, England loop felt a lot like a WWII movie, which was thrilling
Book #3 - An intense and exciting conclusion, with an open ending that leaves you wanting the story to go on
Book #4 - Eases you back into the story with a fun road trip through the loops in America. It felt like a crime thriller but with peculiars, and it also begins to set up the bad guy for the rest of the series and introduce new characters (who I love)
Book #5 - This one is a stepping stone from book 4 to 6, but it also has a lot of action and important details that help set up the finale. It also delves more into Noor
Book #6 - I haven't finished reading it yet, but it is already very intense, and it's very good
