Squeak (Squeakverse #1) by Vera Valentine

A dedicated art student at her local community college, Poppy practically lives inside her sketchbook. Drawn to the distracted crowds of the local zoo, her planned day of anonymous figure-sketching is interrupted by the charming Sebastian - and his brooding, borderline-rude friend Keane. Little does she know the two have a twisted secret that defies imagination - and the pressure on both of them is increasing by the day. As an intricate plan takes shape to secure their freedom, the twists and turns they face - and a pair of very intriguing knots - might just unwittingly tie Poppy to both of them, forever.

Squeak is an menage (m+m+f) balloon animal shifter omegaverse novella with (artistic takes on) OV designations and omegaverse-specific concepts like knotting, heats, ruts, nests, mate bites, bondings, and more. There is a brief (non-main-character) death at the very end. There is discussion of past violence and sexual compulsion/slavery, but it’s all occurred by the time the story starts. MM relationships do not need a warning, but consider this your heads up that the MCs are together, as they often are in my books - this story is polyamorous / polyam.
