The Far End by Johnny Gnall

Growing up on her family's wildlife ranch in rural Northern California, sixteen-year-old Persephone Foss felt a strong connection to animals from a very early age. Lately, however, that connection has been showing itself in strange, even scary, ways; most days she would rather just ignore it. But when her botanist mother brings her along on a research trip to the uncharted Amazon rainforest, Seph astonishes herself with what she is capable of- until a horrific accident leaves her mother clinging to life. Forced to confront her gift with animals head on, the spark inside Seph grows in power and complexity, and strange thoughts and visions begin to find their way into her mind. When those visions point her back toward the Amazon, and an ancient, secret society hidden therein, Seph discovers she may be the only one who can save her mother's life.
