A woman raised by apes?

I tried several times to get interested in Origin, a book that has been on my shelf for years. The book's description sounded interesting enough and it's by an author I'm not familiar with so I thought I'd finally open it up. I tried and tried and tried. Here's what got me every time: the main character was raised by apes. I'm not even joking. There's no way I could pull that off. My main focus in my writing is believability, and asking my readers to engage in a woman that was raised in the rain forest doesn't seem possible. Before deciding to quit the book, I went to Goodreads to read some reviews and was surprised to see that many people enjoyed the story. There were some, like myself, who questioned what the author was thinking. Needless to say, I won't be recommending this book. Apes? Really?
