Would you like to know about me?

Greetings! My name is Dennis Owen!
Alyssa Hamilton, a 14-year old girl living at a boarding school, receives a strange letter from her mother, Nancy. This letter tells Alyssa to Hide until her fifteenth birthday passes. Alyssa is naturally worried, and so decides to go against her mother's wishes and return to her childhood home, a boarding house. When she arrives, her mother is missing-in fact, the only other living person in the house is a mysterious stranger, known as the Dark Gentleman. He offers Alyssa cryptic warnings and clues as to her mother's fate.

Though frightened, Alyssa becomes determined to find her mother. She explores the house and finds a vial of Holy Water, along with strange symbols on doors that only the sacred water can break. Eventually, her search leads her into her mother's room, where a piano begins to play wildly. Terrified, Alyssa dashes from the room-and is transported back in time, to London, circa World War II. While there, she begins to explore the city, which is constantly bombarded. Her search leads her to a tailor shop-where she witnesses the gruesome murder of a young girl. The crime is perpetrated by a mysterious man wielding a sledgehammer; he notices Alyssa, and begins an obsessed search for her. As Alyssa evades him, she runs into other angry ghosts; by returning particular items to each spirit, she is able to placate them and lay them to rest. Eventually, Alyssa pieces together the mystery: May Norton, a 12-year-old piano playing prodigy, was brutally murdered on Christmas Eve by a mad man with a sledgehammer. By restoring a precious pocket watch belonging to the young girl's father, the girl's spirit is eased. This breaks the power of the mysterious Sledgehammer, who engages Alyssa in battle. Her vial of Holy Water becomes a crossbow, and she destroys the villain in a shower of golden light. May's spirit reunites with her father's ghost, and the two thank Alyssa before ascending into Heaven. Alyssa also claims a small portion of a pendant.

When Alyssa returns to the present day, she begins to delve into what happened, and learns a surprising secret about her family. The girls in her lineage are known as "Rooders", young women with the supernatural ability to communicate with the dead. She also learns of a ferocious dark power-called an "Entity"- that can infect certain humans and drive them to acts of crazed murder. The agony and despair of the souls of the murderer's victims feeds their dark power, and grants the villain-now known as a "Subordinate"-immortality. The Rooders are fated to find and free those tortured souls, breaking the Subordinate's magic and allowing them to be destroyed. These powers peak at the age of fifteen, and wane afterward; therefore, the women in Alyssa's family marry young and quickly bear a daughter.

Alyssa realizes that she is a Rooder, and that Sledgehammer was a Subordinate, feeding off of young May's soul. With new knowledge, she moves back in time again and confronts the Corroder, a frightening man who murdered an elderly woman and her son by throwing them in a vat of sulfuric acid. Files reveal that the Corroder was related to the two, the younger man being his cousin. Alyssa finds an old shawl that proves to be the key to freeing the mother and her son, and destroys the Corroder.

Upon returning home, though, Alyssa begins to wonder as to why her mother wanted her to stay away. Soon, she realizes that the mysterious "Dark Gentleman" hopes to gain immortality by becoming an Entity using the the Ritual of Engagement. That dark ritual requires the "heart of a Rooder" of the same bloodline: Alyssa's heart. Alyssa meets other Rooders who were subjected to this torment as she fights the evil Chopper, the leader of the earthly Subordinates. The spirits of the young women help her overcome the villain, and she is able to vanquish the villainous Chopper.

After completing this mission, Alyssa is warped back in time once more-to the home of the mysterious Lord Burroughs, who lived on the very land that the boarding house stands on in the present day. Now, though, it is the location of the titular clock tower. Burroughs, obsessed with the secrets of the Entities and Subordinates, hires two to murder people for him-the homicidal twins, Scissorman and Scissorwoman. Burroughs plotted to become an Entity himself; however, his daughter died on the eve of her fifteenth birthday, ruining his plan and driving him insane. He dies crushed on the clock tower's engines, swearing revenge. With the help of me, Alyssa overcomes the Scissor twins.

Once Alyssa returns to the present day, she discovers that the villain behind her mother's disappearance is her own grandfather, d**k Hamilton who lived with the pair since Alyssa was a child, and performed extensive research on the Rooder powers. However, he was descended from Burroughs, and was eventually driven insane by the "connections" between his and his ancestor's situations and allowed Burrough's evil spirit to fuse with him. He destroys Alyssa's mother and plots to fulfill Burrough's plan with Alyssa's heart; however, Nancy transfers what is left of her own Rooder power into Alyssa, granting her the strength to destroy her grandfather and Burroughs. After she defeats him, she immediately reunites with her mother, then the tower collapses, and the evil spell of the Subordinates Alyssa destroyed is finally lifted forever. However, as Entities still exist, the Rooders' fight is far from over.

The final scenes shows Alyssa waking up in a field of flowers clutching her clover pendant, as she then runs over to hug me nearby.
