Radio Silence by Alice Oseman (YA)*
Overexposed by Megan Erickson (m/m)
Far From Home by Lorelie Brown (f/f)
Concourse by Santino Hassell (m/m)
Empty Net by Avon Gale (m/m)
*The demisexual character in Radio Silence is not the narrator, but he’s the second biggest character in the book, and as far as I know, the only character with this label in mainstream YA, so I opted to include it here
