My Psychotic Obsession: The Edge of Darkness Trilogy Book Review - No Spoilers
Plot Summary
Psychotic Obsession by Leigh Rivers is a powerful, twisted, and deeply emotional dark romance. It takes place about twenty years before the original Edge of Darkness trilogy and follows Aria Miller, a brilliant scientist whose world is upended by Tobias Mitchell. Tobias appears first as her new assistant, but he quickly becomes much more—her captor, her obsession, and her undoing. From the beginning, everything about Tobias is dangerous: his genius, his charm, and the darkness he never tries to hide. Their relationship walks the knife’s edge between love and destruction, their connection laced with obsession and the constant threat of violence. Aria struggles to hold onto herself as Tobias—unhinged, magnetic, and deeply broken—makes it clear that he will do anything to keep her. It’s a story packed with betrayal, impossible choices, and the rawest edges of love and madness.
Why I Love This Book
I love how Psychotic Obsession grips me from the first page and never lets up. The intensity is overwhelming in the best way possible. Tobias is a character I shouldn’t love, but I can’t help it—his darkness is so honest and deep that it pulls me in, even as I’m terrified by what he’s capable of. The way Leigh Rivers balances vulnerability with brutality in his character completely wrecked me.
Aria’s journey is just as gutting. She makes impossible sacrifices and tries to stay true to herself while being sucked into Tobias’s madness. I feel every one of her choices, her pain, and her desperate hope. Nothing in this book is easy—every chapter is a punch to the gut, and the emotions are raw, unfiltered, and sometimes ugly.
It’s not just a romance. It’s a psychological survival story—a study in possession, obsession, and what happens when love is weaponized. The writing doesn’t shy away from darkness, but there are also moments of beauty and even tenderness that make all the pain worthwhile. The epilogue left me devastated and starving for more. I love that this book never gives me the safe or predictable answer. I’m left shattered but strangely satisfied.
Who Will Like This Book
If you crave dark romance that isn’t afraid to make you uncomfortable, this book is for you. You’ll connect with it if you want a story filled with toxic obsession, psychological tension, and deeply flawed characters who will both break your heart and make you root for them. This is not for readers who want sweetness, redemption, or easy love. It’s for those who want to feel every ounce of pain, hope, fear, and twisted passion.
If you enjoyed the Edge of Darkness trilogy, this gives Tobias’s origin story and lets you see how Aria and Tobias’s relationship began. I recommend reading the trilogy first for the full, emotional impact, but you can also start here as this serves as a prequel. Be warned: there’s no HEA here, but it sets up so much for the later books.

The spice is intense—sexual tension seeps through every interaction, with open-door scenes that are raw, sometimes uncomfortable, and full of power plays. This is not romance for the faint of heart: the physicality matches the darkness of the story, and consent is sometimes murky, reflecting the toxic push-and-pull at the book’s heart. If you want open-door scenes that burn and bite, paired with real psychological risk, this book delivers.
