The Volunteer — Melissa A. Craven

Her ancient Mayan family struggles in the modern world but… Is the cost of living forever worth her sacrifice? Santi is a young Immortal on the brink of setting out on her own, but her family is drowning in debt and overwhelmed by the stress of living paycheck to paycheck. When Santi meets the indomitable Immortal, Livia, head of a company called Soma, she is ready and willing to accept her position as one of Livia's most trusted agents -- along with the income that will save her family's home. Among the most technologically savvy of her kind, Santi must prove her worth. But Santi has no idea what she's volunteered for.
