Y e s to all of that. Murderous calculator is best boy. The fakeout at the end got me a little, but the payoff! And okay I'm just rambling but the series as a whole is just so good about suspense and what next?! WHAT NEXT HOW ARE YOU GOING TO SOLVE THIS AIDAN WHAT THE and I love it so much.
Okay and not just suspense but horror, it does it so well, like you get chills from "don't look at me" askdjfg and those storming whatever they were called I don't remember but in the second book, the gahhh creepy things.
I need to reread this too...
