Horror

I will always recommend the Necrososcope series by Brian Lumley - vampires, werewolves, mind powers, and the protag talks to the dead - he makes friends with a dead scientist, learns an equation, and can use the mobius equation to open doorways to anywhere - the first couple of books are slow, but it is soo much fun to read!

Currently listening to The Fisherman by John Langan.

If you enjoy stories within stories - this nails it. I'm dreading what is still too come, and loving it!
