The Invisible Life of Addie LaRue – V. E. Schwab

Adeline LaRue is born in a small village in France at the end of the seventeenth century, where she grows up feeling that she's meant for more than living dying and being buried in the same place. She wants to be free, to be her own person, so when her family starts talking about marriage she is scared, and starts praying to the old gods. She is warned: no matter how desperate or dire, she must never pray to the gods that answer after dark. And yet she does, and this is how her real story begins.
