It's the summer of 1987. Angie's summer intensive on the mysteries of Agatha Christie has her seeing clues everywhere she looks, and there are plenty of clues to be sorted through when one of the Witches in Lorrain's coven is killed. Was it an accident that Shelly's car crashed into Dead Man's Run? Or something darker? And what has become of Shelly's dog, Tati? Angie, David, and Jenny have their work cut out for them to get to the truth, but what they find only leads to more mysteries.

Something Fatal is the sixth of seven stories drawn from Angie's diaries. Kept safely hidden for decades, they tell how the kids spent their teenage years – working with their mentor, Mr. Rakow, and Jenny's mom, Lorraine, who leads a coven, to realize their power and battle the forces of darkness that menace their hometown.
