Mating Bite by Lilia Ford

Mating Bite - Lilia Ford

A well written Teen Wolf fanfic featuring the unusual pairing of Jackson and Isaac (jisaac.) Stiles and Isaac have founded the 'ORT' (Omega Rights Today) along with Lydia, Danny and Erica at their omega only high school. The graduating omegas are expected to attend a 'mixer' that evening in order to socialise with the local unmated Alphas. Some great world building.

“Execution, blood orgy, butchery, massacre—take your pick. Basically, they are taking 25 omega teenagers with less defensive skills than the average new-born kitten, and trapping us in a room full of hormonally-charged, ultra aggressive Alphas on the hunt for mates,” Stiles said, his voice pitching high.
