Perfect for you if...

You love dark paranormal romance with serious power imbalances and possessive love interests who back up their obsession with actual devotion.
You're drawn to stories where the heroine is capable and defiant, forcing her supernatural suitors to earn her trust rather than simply claim it.
You want smut that feels intimate and consequence-laden, not just explicit: these three care deeply about the woman they're pursuing.

Maybe not for you if...

You need your romance heroes to be entirely good men, or at least feel guilty about their darker impulses from the start.
You prefer slow-burn romance where attraction builds gradually rather than instant fated mate recognition that's physically undeniable.
You're uncomfortable with pregnancy or breeding-focused paranormal dynamics, even when the heroine maintains agency.

About this book

During Monsters Night, an annual event when portals to other realms open and monsters search the streets for potential mates, the protagonist becomes a candidate. She earned this status by breaking rules and resisting an elitist system designed to enslave humanity. Three monsters—Orcus, Flame, and Reaper—save her from a dangerous situation, believing her to be a rare Omega and Goddess destined as their mate. They pursue her despite her determination to escape them. Their Lethal Pet is a standalone dark paranormal romance featuring three Nightmare Fae and their chosen female mate.
