I write omegaverse short stories (usually 10-15,000 words) across three heat levels.

Surrendered Heart Omegas Series (light pink covers) are sweet, with a little spice, and a guaranteed HEA

Omega Bonded Series (dark pink covers) are darker, steamier, but still end with a HEA.

Mastered by the Alpha Series (Red Covers) are dark, dub-con, and not found anywhere else. The alpha gets his omega in the end, through heat bonding and situational manipulation.
