Monster Trilogy Books in Order

The Monster Trilogy is a three-book descent into obsession between Sasha and Kirill, set against a backdrop of military hierarchies and Russian mafia power struggles. It is one of Rina Kent’s most tightly plotted arcs, and it rewards readers who like their romances long, layered, and unforgiving.

Blood of My Monster introduces Sasha on a mission for revenge. Disguised as a man in the military, she wants to get close enough to the people who destroyed her family to tear them apart. Instead, she ends up under the command of Kirill, a brilliant, emotionless strategist whose charm is just another weapon. He recognizes the danger she poses and, rather than removing it, pulls her closer.

In Lies of My Monster, the fragile trust they have built splinters under the weight of secrets. Sasha is determined to uncover what really happened to her family, while Kirill is focused on maintaining control over his empire and his feelings. They are no longer on the same side, but staying away from each other proves impossible.

Heart of My Monster raises the stakes to their peak. Kirill has clawed his way to the top and plans to stay there, no matter how much blood it costs. The only thing that truly threatens his position is the woman he cannot let go. Sasha may believe their story is over, but the final book makes it clear that walking away from a man like Kirill is never simple.

The trilogy is steeped in mafia politics, covert operations, and the kind of slow-burn character development that makes every betrayal sting. It also deepens the Volkov side of the Rinaverse and feeds directly into later generations; the ripples from Sasha and Kirill’s choices are felt in books set years down the line.

If you enjoy romances where both main characters are dangerous, competent, and willing to cross lines most people would not even approach, the Monster Trilogy delivers that in full. This page maps out the order, highlights the main beats of their journey from enemies to reluctant partners to something like equals, and shows how their story plugs into the larger mythos Rina Kent has built.
