Sangu Mandanna's debut novel, The Lost Girl, is a provocative and page-turning thriller/romance that gets at the heart of what it means to be human. Using similar themes of Mary Shelly's Frankenstein, the story is wholly original and one that is not easy to forget.
Description (from the publisher):  Eva's life is not her own. She is a creation, an abomination—an echo. She was made by the Weavers as a copy of someone else, expected to replace a girl named Amarra, her "other," if she ever died. Eva spends every day studying that girl from far away, learning what Amarra does, what she eats, what it's like to kiss her boyfriend, Ray. So when Amarra is killed in a car crash, Eva should be ready. But sixteen years of studying never prepared her for this.
  Now she must abandon everything and everyone she's ever known—the guardians who raised her, the boy she's forbidden to love—to move to India and convince the world that Amarra is still alive. What Eva finds is a grief-stricken family; parents unsure how to handle this echo they thought they wanted; and Ray, who knew every detail, every contour of Amarra. And when Eva is unexpectedly dealt a fatal blow that will change her existence forever, she is forced to choose: Stay and live out her years as a copy or leave and risk it all for the freedom to be an original. To be Eva.

Review: Eva doesn't have a right to her own life. She is an echo, a carbon copy of a girl named Amarra who lives halfway across the world. Eva is created as a back-up plan for Amarra's parents in case Amarra dies. Eva mimics Amarra's life, she learns everything that Amarra learns and is even nearly forced to suffer the same physical injuries as her other. Though the concept of clones isn't breaking new ground, what makes The Lost Girl stand out is the exploration of the psychological aspect to Eva's character, since it's not just Eva's organs that are being harvested, but her entire entity and identity.
 The Lost Girl is a novel that sits uneasily along the genre lines of dystopia, science fiction, and speculative fiction. While it contains elements of each of these genres, the world of echoes and their creators called Weavers take on a somewhat mystical and mysterious manner. The book never really delves into how the world came to exist. Like some of Bradbury's stories, we are shown human beings who find themselves in extraordinary futuristic circumstances instead of a technology driven setting that drives humans. I know some readers may be disappointed in not knowing much about Weavers and the utterly creepy setting of the Loom, but this didn't bother me at all. I was thoroughly captivated by the characters of this story and it didn't deter me from enjoying the story. 
  Mandanna's writing is exceptional, thoughtful, and beautifully descriptive, deftly balancing seriousness and humor, just like her characters. Eva is a heroine that I loved from the start. She finds herself in a horrible circumstance, but makes the best of it without losing her dignity and constant persistence. Unlike many heroines that fill our pages with noble self-sacrifice, Eva refuses to give up her inalienable rights to have a life and a place in society regardless of how he kind is perceived. She is rightfully selfish, but also aware of the dangers she puts her loved ones while she goes an incredible journey.
