Red Rain by R.L. Stine
Those among us who grew up reading the Goosebumps series were pretty darn excited when we heard that R.L. Stine was releasing his first ever novel for adults. Luckily, it does not disappoint, as it creates great atmosphere and ends up being perfect for those of us who loved his stuff as youngans.
Scare Factor: 3 - Definitely more mature than the Goosebumps series, but not the scariest thing ever.
