Heart of My Monster (monster Trilogy, #3)

This is the third and final book in a trilogy. Events from the previous installments, including Sasha's years living disguised as a man and her secret marriage to Kirill, form the foundation of this volume.

The novel opens with a prologue set during Sasha Ivanova's childhood. At sixteen, Sasha celebrates Christmas with her extended family at a vacation house in northern Russia when armed soldiers storm the dining room and massacre nearly everyone present. Her parents are killed before her eyes, and her cousins shield her with their bodies, dying in the process. Sasha survives only because she lies beneath their corpses, soaked in blood, silent and trembling.

In the present, Kirill Morozov stands at the altar for his arranged marriage to Kristina Petrova, a union brokered with her father Igor and the outgoing Pakhan, the supreme leader of their Bratva, or Russian organized crime brotherhood. Kirill has orchestrated events so that Kristina, who is secretly in love with his younger brother Konstantin, will refuse her vows. When she flees, Kirill reveals he knew about their relationship and manipulated the situation. He reframes the crisis, claiming Kristina is already pregnant with Konstantin's child. Igor agrees to let Kristina marry Konstantin instead, and Kirill's inauguration as the new Pakhan proceeds with six of eight leadership votes.

Immediately afterward, Kirill's senior guard Viktor delivers devastating news: The remote cottage where Kirill sent Sasha has been bombed. Kirill races to the scene and finds a burned body wearing Sasha's ring and bracelet. A DNA test confirms a match, and Kirill buries the remains under the name Aleksandra Morozova.

Over the following weeks, Kirill comes home covered in blood every night, hunting anyone connected to the bombing. He tracks the attack to an Albanian crime leader whose cousin he previously killed. After a brutal interrogation, he learns that a mysterious figure directed the Albanians to kill Sasha at the cottage.

Sasha, however, is alive. Her brother Anton, whom she believed died in the family massacre years earlier, pushed her to safety before the second bomb detonated. Before fleeing, Sasha placed her ring and bracelet on a corpse of similar build and burned it, intending to wound Kirill. She believed he ordered her death because she saw Makar, a guard under Kirill's command, speeding away from the scene. Combined with Kirill's engagement to Kristina and the Morozov family's involvement in her family's massacre, Sasha concluded Kirill had betrayed her.

Sasha and Anton hide in a Siberian safe house with their Uncle Albert, their grandmother Babushka, and their young cousin Mike. Anton's history is revealed: He survived the massacre, recovered from a coma, then killed one of Kirill's guards and assumed the man's identity through surgery and disguise, infiltrating Kirill's inner circle for five years. Uncle Albert explains that the Ivanov family were Russia's secret power brokers until the current president sought to destroy them. Roman Morozov, recruited for his mercenary forces, betrayed the family and carried out the massacre on behalf of the government.

Sasha discovers Anton torturing Maksim, Kirill's loyal guard, who had been sent to Russia on a reconnaissance mission. She forces Anton to release Maksim, and the three settle into an uneasy coexistence. Trusting Maksim's loyalty and fearing that captivity is driving him toward self-harm, Sasha helps him escape. She sends him back to Kirill with a message: She is alive and intends to kill him.

When Maksim delivers this news, Kirill laughs with relief. Sasha, Anton, and a group of mercenaries fly to New York for their attack. Sasha positions herself with a rifle near a cliff, but Kirill appears behind her. He stands unarmed, showing her the wedding ring she placed on his finger, and tells her she is his only wife. He walks toward her, telling her to shoot if she truly feels nothing. Sasha wounds his arm but cannot deliver a fatal blow.

Kirill reveals he has captured Anton and brought an overwhelming force. Sasha negotiates: She will stay with him for three months, after which he must grant a divorce. At the mansion, she learns the truth she missed: Kristina married Konstantin, not Kirill. The entire groom swap was Kirill's design. Her central justification for hatred collapses.

Kirill takes Sasha to a remote cabin for over two weeks. He cooks for her, brings her flowers, and takes her hiking. Their physical relationship reignites after a forest ambush forces Sasha to confront how much she fears losing him. Kirill arranges a surprise Christmas celebration, inviting family to the cabin. For the first time in nearly seven years, Sasha celebrates the holiday.

Back in New York, Sasha discovers she is fifteen weeks pregnant and hides this from Kirill, fearing he will use the baby to bind her. Meanwhile, Konstantin reveals that their mother Yulia has been secretly giving Kristina toxic herbs to harm her unborn child. Kirill expels Yulia. During the confrontation, Yulia reveals that Roman raped her repeatedly, resulting in Kirill and his sister Karina. She says Konstantin is the only child she conceived with the man she loved and tells Kirill she should have killed him at birth.

Kirill receives a message from Makar, who confesses involvement in the cottage bombing but names Konstantin as the mastermind, presenting fabricated evidence. Kirill kills Makar and imprisons Konstantin. Sasha insists Konstantin is innocent. Privately, Kirill finds a hidden memory card and letter inside a copy of Crime and Punishment that Roman kept in a safe, revealing the full conspiracy.

Sasha and Viktor are captured on the road and awaken bound before Babushka, Uncle Albert, and Yulia, who have allied to kill Kirill. When Kirill arrives, he plays a recording from Roman's hidden files. The recording reveals that Yulia had a years-long affair with Sasha's uncle Anatoly Ivanov, making Konstantin Anatoly's biological son. When Anatoly ended the affair, Yulia told Roman, who used the government's campaign against the Ivanovs as cover for personal revenge. The recording confirms Uncle Albert served as Yulia's insider during the massacre. Albert confesses he orchestrated his own family's slaughter out of resentment toward his mother and brothers, who always overshadowed him. When Babushka confronts him, Albert shoots her dead.

Anton, Maksim, and Konstantin arrive. Kirill had freed Anton and orchestrated the standoff to expose the traitors. In the chaos, Yulia tries to shoot Kirill, Albert fires simultaneously, and Maksim throws himself in front of Anton, taking a bullet. Sasha begins bleeding from a pregnancy complication and loses consciousness.

Sasha wakes in the hospital. Her baby has survived, and Kirill now knows about the pregnancy. The doctor reports Maksim is stable. Anton tells Sasha he will leave the life of revenge and start fresh with Maksim and Mike.

Kirill confronts Sasha about hiding the pregnancy, telling her he does not want her to stay because of the baby. He tells her he is nothing without her. Sasha confesses she never stopped loving him, and they reconcile.

In the months that follow, Yulia dies. Maksim recovers and moves to Russia with Anton and Mike, where Anton rebuilds the family's legitimate enterprises. Sasha gives birth to a son, Vaughn. Eighteen months later, the family gathers for Christmas. Kirill reflects that he spent his life chasing power, only to discover his purpose was Sasha, who challenges him, loves him, and made him proud to be both a father and a husband.
