Assimilation tells the story of Kercy, a fragile and often isolated young woman whose life is split between the harshness of her family and the eerie beauty of the Soshone Islands. The calm of her summers fractures when she hooks a grotesque, severed limb in the lake, only to be visited that same night by strange beings who invade her room and her body. That moment becomes the axis of her entire life, leading her toward hidden truths about her parents, her own biology, and the horrifying forces lurking beneath the water. The book follows her journey from isolated child to self-possessed adult as she navigates love, danger, loss, and the long shadow of whatever visited her that night.

Reading it pulled me around emotionally in ways I didn’t expect. Some sections felt tender and slow, almost sleepy with the warmth of summer afternoons, then suddenly the story lurched into fear and chaos. I kept feeling this knot in my stomach because the writing toys with dread in such a quiet way. Busch’s descriptions of water and landscape are gorgeous and simple. They gave me a sense of calm. Then he ripped it away with scenes so bizarre I actually had to pause. The alien encounter scene hit me hardest. It felt weirdly intimate, almost like watching someone relive a trauma they barely understand. It made my skin prickle because it blended dream logic with physical detail in a way that felt too real.

But the part that stayed with me most wasn’t the creatures. It was the messy and painful bond between Kercy and her parents. Her father’s coldness stung every time he appeared. Her mother’s love felt too thin in some moments and heartbreakingly fierce in others. The whole time, I felt this quiet anger building under the surface. He disappears early in the book, yet his absence keeps shaping her life like a bruise that never fully heals. By the time the story reaches its later chapters, where Kercy reflects on the ruins of her past from adulthood, I felt this soft ache for everything she carried that nobody helped her set down.

Assimilation struck me as a story for readers who love emotional tension mixed with strange, unsettling mystery. Assimilation blends the emotional depth of The Girl with All the Gifts with the eerie, slow-burn dread of Annihilation and the intimate character focus of Room, creating a story that feels both tender and terrifying. If you like atmospheric fiction with sci-fi elements woven into human pain, or if you enjoy stories that linger in your mind, this one will absolutely grab you.
