Rapunzel Untamed by Erin Bedford

A thousand years. No memories. Five powerful mages dying to save her.
In the city of Neo New York, mages rule the world. People like Eva, the non-magical kind, mean nothing. The only destiny waiting for her will be to serve the mages for the rest of her days.
Except Eva isn’t like other humans. Locked in a tower for a crime she doesn’t even remember, Eva is saved by none other than some of Neo New York’s most prestigious mages, and they won’t let anyone take their new toy away from them.
When Eva’s memories make a reappearance, she realizes she might be a little bit more than just a nuisance. Now, Eva must dodge jealous ex-lovers and ambitious council members, all while keeping her past a secret.
Whoever said fairy tales had happy endings hasn’t walked a minute in Eva’s shoes.
