I usually read a physical copy throughout the day, and something on the kindle before going to bed.

Something Wicked was the first one I've read so far from this series. From my understanding they are not connected in terms of story. So I think you can read in any order.

Something Wicked This Comes, by Ray Bradbury - Has the perfect Halloween/autumn atmosphere. Wonderful story and prose as well.

Salem's Lot, by Stephen King - Terrified me. My favorite Stephen King story.

I Am Legend, by Richard Matheson - Another great vampire novel. Has one of my favorite endings ever.

The Color Out of Space, by H.P Lovecraft - I personally think this is Lovecraft's creepiest story. Highly recommend.
