That was SUCH a great thriller!! It was so well written and the plot really was interesting to try to guess!! Compared with other thrillers, there was no exageration of personnal characteristics. I also LOVED to hate some characters, and loved the nuance in each and every characters. I had so much fun taking notes of everything and trying to guess who killed her sister! I took notes on some of the reactions I had while reading, so here they are:
QUEEEEEEEER! 

Omg not the serial killer wanting her to feel safe as a woman HAHAHAH

Oooooh is Ernie the guy owning the deli Cyra went to?

So he’s targeting men that does the same as him…? Typical

Erm that jump in time was fucked up

LOL the emotions for the eggs but not for her dead sisterXD

HAHAHAHAH not her asking him not to kill her cause she got things to do HAHAHAHAH

She’s manipulating Eli…

Chapter on Pea was nicely written!
