⭑𓂃 Hi hi ~

I’ve had a particular history with OUABH, Jacks… and of course sweet Eva, you see (⊙ _ ⊙)

And sadly, I’m a thorough hater who’s ready to be more hated on than Apollo himself ( •᷄ᴗ•́)

₍ 🏹💗 ₎ ˙— ✶ pre-release ₊˚ᰔ

(let’s pretend i’m not so late okay)

i’m writing and deleting and writing and deleting because i don’t really know how to express how joyful and jubilant i feel right now.
i’ve been needing this novella like the air i breathed ever since i finished this trilogy. a trilogy that took everything out of me when it ended (man, the pain of waiting months for book 3...) but at the same time that makes me smile like a little kid only thinking about it and that now has a special place in my heart.
i can’t wait to get my hands on this book and hope the months fly by to get to sep 29th quickly!!
