About a Girl by Sarah McCarry
Everything is going great for eighteen-year-old Tally: she has the unconditional love of her adoptive family, a loyal best friend and dreams of becoming a Nobel prize-winning astronomer. But when an unexpected discovery involving the mother that abandoned her soon after birth propels Tally on a journey to find the one person who can answer questions about her family and her past, Tally meets a girl named Maddy who turns her world upside down. Beautiful and enigmatic, Maddy shows Tally that life can be bigger and more complicated than she anticipated, and that the future is never set in stone.
