The Lion, the Dragon, & Their Unicorn Omega by Lorelei M. Hart

Breaking the bonds of slavery takes more than just physical freedom, which is something newly freed slave Samuel is about to discover.

Unicorn shifter Samuel has spent most of his life as a slave for the red dragons, being passed from household to household like the property her is. When he starts working in Bart’s mansion he expects it to be more of the same—instead he finds himself seeing more and more glimpses of the future, a future that does not include being owned. A future he never dared dream of.

Lion shifter Sasha loves his life in Haven and the semi-retirement it allows him. Being a paid mercenary was both exciting and lucrative, but he is ready to grow roots. When an elderly unicorn calls, begging him to help her captive grandson he decides to take one last case. He saw what the red dragons did to his friends’ mate, Grey, and his conscience won’t allow him to sit back and let it happen to another even if is means coming out of semi-retirement and risking the life he’s been building.

Dragon shifter Rob lives the high life complete with penthouse suite, a treasure any dragon would be envious of, and a job that gives him the adventure he craves and the downtime he relishes. It is the life he always dreamed of, yet completely unfulfilling. When his on-again off-again lover and coworker Sasha asks him to help on one last mission together, Rob is powerless to say anything but yes. They set out to rescue the elderly unicorn’s grandson and end up finding the one thing they were both missing in their lives—their omega.
When Samuel escapes his master’s mansion and runs into not one but two shifters there to rescue him, he knows instantly that it is more than just luck. Fate is on his side.

Fate has sent him his true mates, soon giving him the gift of fatherhood. Unfortunately, that doesn’t mean he has his instant happy ever after. There are people to save, emotional wounds to heal, and a new life to build—one that for the first time is based on what he wants for himself.
