Warm Blood Gn Vol 01 by Josh Tierney

The popular high-school mystery webcomic comes to print for the first time! Join Penny, a quiet girl who dreams of becoming a video game developer, as she navigates her first year at Greenwood High. There she must contend with a string of bizarre murders, potentially evil twins, rumors of shadow monsters, and a strange presence lurking just outside her window. Helping Penny through it all are her friends, including her anime loving best buds from elementary school, a 4th wall smashing girl she meets on her first day, and a sweet awkward girl eager to be her BFF, and who happens to be very handy with a baseball bat.
