Lady of Myrdin - Cathinca van Sprundel - Bog

Princess Airys lost everything, her parents, and her principality of Dyfed to darkness. Queen Aranrod has promised to help her win back Dyfed in exchange for seven years of service. Now that it's finally time, the queen's promise comes in a different form.
Instead of helping restore Airys' birthright to Dyfed, she is given rule over an abandoned island called Myrdin. Known as the cursed island that no one wants to inhabit, Airys must overcome her fears and fall back on magical strangers and ancient knowledge to survive on the island and lay claim to all that is rightfully hers.
