Wish Upon A Well by Samantha Wymer

Orla O’Brien has spent her entire life searching for where she belongs. Raised in the foster care system until she is emancipated by the state of California, Orla leaves behind a lonely life in San Diego with nothing but questions about her past. As a final gift, she receives an ancestry DNA kit that changes everything.
Months later, Orla meets her mysterious grand-uncle, Conor O’Brien, who reveals the truth about her family. Her parents were Irish, and Orla is the last heir to the powerful O’Brien bloodline. Hoping for a fresh start and longing for the family she never had, Orla leaves America behind and journeys to Ireland.
But Ireland holds far more than answers.
Hidden deep within the emerald countryside lies an ancient wishing well tied to secrets older than time itself. There, Orla encounters Rian—a hauntingly familiar stranger who is far more than he seems. As memories from another life begin to awaken, Orla discovers she is the reborn Golden Princess, descendant of the goddess Dana, destined to become queen of a mystical realm that protects the Aos Sí and the ancient magic of Celtic legend.
Caught between destiny, love, and the shadows of her forgotten past, Orla must embrace who she truly is before darkness destroys both worlds.
Wish Upon A Well is a spellbinding fantasy woven with Celtic mythology, romance, magic, and the power of discovering where you truly belong.
